Each multiple-choice question on an exam has four choices. Suppose that there are 10 questions, and the choice is selected randomly and independently for each question. Let X denote the number of questions answered correctly. Does X have a discrete uniform distribution? Wwhy or why not? a. No. X is a discrete random variable with range {0, 1, 2,.., 10}. But not uniform. P(X=0) is not equal to P(X=1) O b. Yes, uniform distribution. AS each exam questions each have equal number of 4 choices. O c. Yes. X is a discrete random variable with range {0, 1, 2,.., 10}. P(X=0) is equal to P(X=1) .... O d. None among the choices
