Expected value.

Explanation: Variables with countable number of possible values are said to be discrete, when these variables are generated through a randomized patten or system, hence they are called discrete random variable. With the summation of individual probabilities within the variables totalling 1, each variable possessing a weighted probability value. When the probability value of attached to each variable is multiplied by the variable value, then the summation obtained from the sequence is called the Expected value.
