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 … Visa mer The idea of the expected value originated in the middle of the 17th century from the study of the so-called problem of points, which seeks to divide the stakes in a fair way between two players, who have to end their game before it … Visa mer As discussed above, there are several context-dependent ways of defining the expected value.

Webbproposed that individuals attribute utility values to each final state of wealth, and attempt to maximize this utility when making decisions. The theory resolved several paradoxes in decision theory, including the notable St. Petersburg Paradox.
