The expected value is a generalisation of the weighted average in probability theory. It is also known by the names expectation, expectancy, mathematical expectation, mean, average, and first moment. Informally, the expected value is the average of a large number of outcomes chosen at random and in different ways. A weighted average of every outcome that could occur is the value that is expected from a random variable with a finite number of outcomes. The expectation is determined by integration when there is a continuum of potential outcomes. The expectation is given by Lebesgue integration in the axiomatic basis for probability provided by measure theory. It had been discussed for centuries.
