Quizplus · Accepted Answer

A probability distribution is a description of how probabilities are distributed over the values a random variable can take on. A probability function and random variable are both components of a probability distribution, but they do not fully describe the distribution. The expected value is a measure of the central tendency of a probability distribution, but it is not the same as a description of how probabilities are distributed over values.
