Quizplus · Accepted Answer

The Poisson random variable is a discrete random variable with infinitely many possible values, where these values represent the number of occurrences of a rare event in a given time or space interval. It is not a continuous random variable, nor does it have a finite number of possible values. Therefore, the best choice is B.
