Question

Quizplus · Accepted Answer

The expected value of a discrete random variable is the average value for the random variable over many repeats of the experiment. It is not necessarily the most likely or highest probability value for the random variable, and it may not always be one of the values x can take on. Therefore, options A and B are incorrect. Option D is incorrect as not all of the options are correct.
