The mean or expected value of X is defined by E(X) = sum xk p(xk). Interpretations: (i) The expected value measures the center of the probability distribution. Expected value is one of the fundamental concepts in probability, in a sense more general than probability itself. The expected value of a real-valued random. Anticipated value for a given investment. In statistics and probability analysis, expected value is calculated by multiplying each of the possible outcomes by the.
