The expected value of a discrete random variable
A)is the most likely or highest probability value for the random variable
B)will always be one of the values x can take on, although it may not be the highest probability value for the random variable
C)is the average value for the random variable over many repeats of the experiment
D)None of these alternatives is correct.

Quizplus · Accepted Answer

The expected value of a discrete random variable is calculated by multiplying each possible value by its probability, and then summing these products. It represents the average value of the random variable over many repeats of the experiment, and may not necessarily be the most likely or highest probability value for the random variable. Therefore, option C is the correct choice.
