Math
The RSS feed extension corrupts the math formula. The error below is displayed on this page because the RSS feed extension is used. Copy the formula to the sandbox, make some changes, and verify Extension:Math is working.

Suppose random variable X can take value x_{1} with probability p_{1}, value x_{2} with probability p_{2}, and so on, up to value x_{k} with probability p_{k}. Then the expectation of this random variable X is defined as
 '"`UNIQpostMath00000001QINU`"'
Since all probabilities p_{i} add up to one: p_{1} + p_{2} + ... + p_{k} = 1, the expected value can be viewed as the weighted average, with p_{i}’s being the weights:
 '"`UNIQpostMath00000002QINU`"'
