This approach enables a Runestone component to load only the JavaScript it needs, rather than loading JavaScript for all the components regardless of which are actually used.\n//\n// To accomplish this, webpack's split-chunks ability analyzes all JS, starting from this file.

(If using static imports, webpack will assume that all files are already statically loaded via script tags, defeating the purpose of this framework.)\n//\n// However, this approach leads to complexity:\n//\n// -    The ``data-component`` attribute of each component must be kept in sync with the keys of the ``module_map`` below.\n// -    The values in the ``module_map`` must be kept in sync with the JavaScript files which implement each of the components.\n\n// Static imports\n// ==============\n// These imports are (we assume) needed by all pages.

doesn't style multiple references to the same reference with brackets. Here's the relevant snippet of CSS:\n\n.. code-block:: CSS\n    :number-lines:\n\n    a.brackets:before,\n    span.brackets > a:before{\n        content: \"[\";\n    }\n\n    a.brackets:after,\n    span.brackets > a:after {\n        content: \"]\";\n    }\n\nThe HTML for a footnote reference is:\n\n.. code-block:: HTML\n    :number-lines:\n\n    <a class=\"footnote-reference brackets\" href=\"#assembled\" id=\"id1\">2</a>\n\nThe HTML for a typical footnote is:\n\n.. code-block:: HTML\n    :number-lines:\n\n    <dl class=\"footnote brackets\">\n        <dt class=\"label\" id=\"xxx\">\n            <span class=\"brackets\">\n                <a class=\"fn-backref\" href=\"#id2\">1</a>\n            </span>\n        </dt>\n        <dd>Omitted this...</dd>\n    </dl>\n\nThe HTML for a footnote referenced multiple times is:\n\n.. code-block:: HTML\n    :number-lines:\n\n    <dl class=\"footnote brackets\">\n        <dt class=\"label\" id=\"xxx\">\n            <span class=\"brackets\">1</span>\n            <span class=\"fn-backref\">\n                (<a href=\"#id1\">1</a>,<a href=\"#id2\">2</a>,<a href=\"#id3\">3</a>)\n            </span>\n        </dt>\n        <dd>Omitted this...</dd>\n    </dl>\n\nHowever, there's no (current) CSS selector that will add a ``content`` to the multiply-referenced footnote without adding an additional ``content`` to the typical footnote: we want to select ``dt.label > span.brackets > text-only content`` or ``dt.label > span.brackets > :not(:has a)`` (see the unsupported `:has selector <https://css-tricks.com/did-you-know-about-the-has-css-selector/>`_. So, I see no solution for this (outside JS).\n\n\nIncorrect color\n===============\nSecond, the Bootstrap theme (v3.4.1) contains the following CSS, from ``node_modules/bootstrap/dist/css/less/labels.less``:\n\n.. code-block:: CSS\n    :number-lines:\n\n    .label {\n        display: inline;\n        padding: .2em .6em .3em;\n        font-size: 75%;\n        font-weight: 700;\n        line-height: 1;\n        color: @label-color;\n        text-align: center;\n        white-space: nowrap;\n        vertical-align: baseline;\n        border-radius: .25em;\n\n        ...more here omitted...\n    }\n\nALL this therefore gets applied to footnotes, since they have the ``label`` class. Because the ``@label-color`` is white, this CSS makes the reference invisible against the default (light mode) white background. I like the rest of the styling changes (even though they differ from the standard Sphinx settings), so only the color is changed.\n*/\ndt.label > span.brackets:not(span.brackets > a),\ndt.label > span.fn-backref:not(span.fn-backref > a) {\n    color: black;\n}\n\n/* These admonition styles styles are copied from the Bootstrap .alert classes.\n Most of the !important declarations are to

This approach enables a Runestone component to load only the JavaScript it needs, rather than loading JavaScript for all the components regardless of which are actually used.\n//\n// To accomplish this, webpack's split-chunks ability analyzes all JS, starting from this file.

(If using static imports, webpack will assume that all files are already statically loaded via script tags, defeating the purpose of this framework.)\n//\n// However, this approach leads to complexity:\n//\n// -    The ``data-component`` attribute of each component must be kept in sync with the keys of the ``module_map`` below.\n// -    The values in the ``module_map`` must be kept in sync with the JavaScript files which implement each of the components.\n\n// Static imports\n// ==============\n// These imports are (we assume) needed by all pages.

doesn't style multiple references to the same reference with brackets. Here's the relevant snippet of CSS:\n\n.. code-block:: CSS\n    :number-lines:\n\n    a.brackets:before,\n    span.brackets > a:before{\n        content: \"[\";\n    }\n\n    a.brackets:after,\n    span.brackets > a:after {\n        content: \"]\";\n    }\n\nThe HTML for a footnote reference is:\n\n.. code-block:: HTML\n    :number-lines:\n\n    <a class=\"footnote-reference brackets\" href=\"#assembled\" id=\"id1\">2</a>\n\nThe HTML for a typical footnote is:\n\n.. code-block:: HTML\n    :number-lines:\n\n    <dl class=\"footnote brackets\">\n        <dt class=\"label\" id=\"xxx\">\n            <span class=\"brackets\">\n                <a class=\"fn-backref\" href=\"#id2\">1</a>\n            </span>\n        </dt>\n        <dd>Omitted this...</dd>\n    </dl>\n\nThe HTML for a footnote referenced multiple times is:\n\n.. code-block:: HTML\n    :number-lines:\n\n    <dl class=\"footnote brackets\">\n        <dt class=\"label\" id=\"xxx\">\n            <span class=\"brackets\">1</span>\n            <span class=\"fn-backref\">\n                (<a href=\"#id1\">1</a>,<a href=\"#id2\">2</a>,<a href=\"#id3\">3</a>)\n            </span>\n        </dt>\n        <dd>Omitted this...</dd>\n    </dl>\n\nHowever, there's no (current) CSS selector that will add a ``content`` to the multiply-referenced footnote without adding an additional ``content`` to the typical footnote: we want to select ``dt.label > span.brackets > text-only content`` or ``dt.label > span.brackets > :not(:has a)`` (see the unsupported `:has selector <https://css-tricks.com/did-you-know-about-the-has-css-selector/>`_. So, I see no solution for this (outside JS).\n\n\nIncorrect color\n===============\nSecond, the Bootstrap theme (v3.4.1) contains the following CSS, from ``node_modules/bootstrap/dist/css/less/labels.less``:\n\n.. code-block:: CSS\n    :number-lines:\n\n    .label {\n        display: inline;\n        padding: .2em .6em .3em;\n        font-size: 75%;\n        font-weight: 700;\n        line-height: 1;\n        color: @label-color;\n        text-align: center;\n        white-space: nowrap;\n        vertical-align: baseline;\n        border-radius: .25em;\n\n        ...more here omitted...\n    }\n\nALL this therefore gets applied to footnotes, since they have the ``label`` class. Because the ``@label-color`` is white, this CSS makes the reference invisible against the default (light mode) white background. I like the rest of the styling changes (even though they differ from the standard Sphinx settings), so only the color is changed.\n*/\ndt.label > span.brackets:not(span.brackets > a),\ndt.label > span.fn-backref:not(span.fn-backref > a) {\n    color: black;\n}\n\n/* These admonition styles styles are copied from the Bootstrap .alert classes.\n Most of the !important declarations are to

Suppose a die has the values on the faces, but the die is not fair. Instead, the probabilities scale by the same amount as the face values. For example, a result of 4 is twice as likely as a result of 2, since 4 is twice as large as 2; a result of 6 is six times more likely than a result of 1; and so on. Write a probability distribution table for this die.      Suppose a die has the values on the faces, but the die is not fair. Instead, each even value has an equal probability, each odd value has an equal probability, and the even values are each twice as likely as the odd values to appear on a roll.

When we talk about a fair coin flip or a fair die roll, the word \"fair\" is indicating a uniform distribution.

Continuous Expected Value  Expected value for a discrete random variable is a weighted average of the values taken by the variable with weights provided by the probability distribution. We'd like to use the same idea for a continuous random variable, but now we're averaging over an interval's worth of values. Also, individual values don't have probabilities, they have probability densities.    Let be a continuous random variable taking values in the interval with pdf . The expected value of is given by:     It's worth viewing this definition side-by-side with to understand that they have analogous structure. The pdf values are densities, not probabilities. But the product is probability. So the expression is analogous to : value times probability. Finally, the integral symbol is meant to look like a stretched out letter \"S\" because it is a form of infinite summation. So, both and should be understood as taking the products of values with their probabilities and then summing up those products.    Let be uniform on the interval . So has the pdf . We might reasonably expect that the average value of would be the midpoint of the interval. Let's check that:       Let take values in with pdf .       Linearity of Expected Value  In the context of many areas of mathematics, the word \"linearity\" doesn't refer to some graph being a straight line. Rather, it refers to a situation in which some mathematical object or operation behaves in the nicest possible way under the operations of addition and scalar multiplication (i.e., multiplication by a constant). You've already encountered linearity several times in Calculus 1, whether or not it was phrased that way.   Limits are linear:     Derivatives are linear:     Integrals (both definite and indefinite) are linear:    Now, we see that expected value is also linear:   Linearity of Expectation   Let and be random variables and . Then:     Some application of the linearity of expectation will seem entirely reasonable:    In , we saw that the expected value of a fair 6-sided die roll is 3.5. In , we saw that the expected value of the sum of two die rolls is 7, which is precisely 2 times 3.5. The calculation in would be very tedious to recreate for three die rolls, let alone generalizing for rolls. However, suppose we define separate random variables for the result of each individual roll. Let be the sum of the rolls. Then By linearity: For two rolls, we recover our previous result: But now we have a general formula that tells the expected sum for any number of rolls. It also gives a perfectly reasonable answer: the expected sum of rolls is times the expected value of a single roll.      Suppose . describes a binomially distributed random variable as counting the number of occurrences of some event, which either happens or not in each of independent trials. This leads us to a very natural idea: identify each individual possible occurrence of the event, and assign it an indicator random variable. In this case, let indicate that flip comes up heads. Then We already know ( ) that the expected value of each is the probability of the indicated event that flip is heads. This is precisely the parameter . Therefore: Remember this formula! We'll make frequent use of it.    The previous examples are so reasonable it may seem unimpressive. But consider the following use of linearity:    We say a flip sequence has a run of 4 heads starting at if flips are all heads. We don't care about overlaps: the flip sequence has a run of 4 heads starting at 1 and another run starting at 2.  Suppose we flip a fair coin 100 times. How many runs of 4 heads should we expect?    Can you mimic the structure of ?    Let indicate a run of 4 heads starting at . Since this requires 4 precise flips to come up heads, the probability of the indicated event should be The very last starting flip for a run of 4 heads is flip number 97 (so that flips 97, 98, 99, and 100 would all be heads). Then precisely counts the number of runs of 4 heads. Using linearity: Notice that, unlike , the events being indicated here are not independent from each other. Linearity is unaffected by the fact that that the runs of heads can overlap.        Consider a random variable with probability distribution below. Find .          1  0.1    2  0.05    3  0.2    4  0.15    5  0.15    6  0.1    7  0.05    8  0.1    9  0.1         Let and be random variables each taking the values 1, 2, 3, 4, 5. Write different distribution tables for and so that they have the same expected value.      Suppose we flip a coin times, and let count the number of heads.

+  "body": " Variance  The expected value is one of several statistics sometimes referred to as a \"measure of central tendency\". These are statistics that try to capture the \"typical\" value of the random variable. Our next statistic tries to measure how spread out a distribution is.    Let be a random variable. The variance of is:     This formula tries to capture some measure of how spread out the distribution is. One way we might hope to measure spread is to calculate how far away is from its expected value on average. Squaring the term ensures that any difference between the value of the random variable and its expected value contributes positively. (\"Distance away from\" should be positive.) So, the formula in is conceptually clear. In practice, there's another way to structure the formula that makes for cleaner calculation:    Let be a random variable. Then:            Let be the value of a fair 6-sided die roll. We've seen in that . To find : Then     Notice that in the calculation, we're just taking the basic structure of the calculation and squaring the values. The analogous calculation for a continuous random variable looks similar:    Let be uniform on the interval . So has the pdf , and we saw in that . Now: Then:     Variance is not linear. In general, you can't split up variance across plus or minus signs, and you can't pull multiplied constants out of the variance like you can with expected value.

But recall that the variance calculation involves squaring; it's an indirect measure of spread. So it's reasonable that scaling the distribution by a constant should scale the variance by its square.  Let's put these properties to use in a pair of related examples:    Let indicate an event which has probability . In , we saw .

The expression can be negative for combinations of and values where one is greater than its average and the other is smaller. If this is the average behavior, then can be negative overall. This is useful information: a negative would imply that (on average, not necessarily always) when is larger than typical, is smaller than typical, and vice versa.
