Question

Give the range of values that the random variable X may assume and classify the random variable as finite discrete, infinite discrete, or continuous. X = The number of times an accountant takes the CPA examination before passing
A) Any integer; infinite discrete
B) 0 ≤ x < ∞; continuous
C) Any positive integer; infinite discrete
D) 0 ≤ x < 24; continuous
E) Any positive integer; infinite continuous

Quizplus · Accepted Answer

The random variable X can only take positive integer values (1, 2, 3, etc.) as an accountant has to take the CPA exam at least once before passing it. Since there is no upper limit on the number of times one can take the exam, X can take infinitely many values. Thus, the random variable is infinite discrete, and the only choice that reflects these characteristics is C.
