Quizplus · Accepted Answer

The expected value of a probability distribution is the theoretical average value that the random variable takes. It represents the center of mass of the distribution and is calculated as the weighted average of all possible values of the random variable, where the weights are given by the probabilities associated with each value. Therefore, the correct option is (C) the average value of the distribution.
