Expected Value
Mean of a Random Variable
A quantity equal to the average result
of an experiment after a large number
of trials. For example, if a fair 6sided die is rolled, the expected
value of the number
rolled is 3.5. This is a correct interpretation even though it is
impossible to roll a 3.5 on a 6sided die. This sort of thing often
occurs with expected values.
