In probability theory, the expected value (also called expectation, expectancy, mathematical expectation, mean, average, or first moment) is a generalization of the weighted average. Informally, the expected value is the arithmetic mean of a large number of independently selected outcomes of a random variable. The expected value of a random variable with a finite number of outcomes is a weighted … NettetIf $X$ has a uniform distribution on the interval $[a,b]$, then we apply Definition 4.2.1 and compute the expected value of $X$: $$\text{E}[X] = \int\limits^b_a\! x\cdot\frac{1}{b …
