**statistics Calculating mean from the probability mass**

The cumulative probability function of a random variable (discrete or continuous) is a function whose domain is similar to that of the probability mass or density function, but whose range is the set of probabilities associated with the possibility that the random variable will assume a value that is less than or equal to the values in the domain.... It is also sometimes called the probability function or the probability mass function. ( Definitions taken from Valerie J. Easton and John H. McColl's Statistics Glossary v1.1 ) Suppose a random variable X may take k different values, with the probability that X = x i defined to be P(X = x i ) = p i .
