6. Which of the following are true statements?

I. The expected value of a geometric random variable is determined by the formula (1-p)p.

II. If X is a geometric random variable and the probability of success is .85, then the probability distribution of X will be skewed left, since .85 is closer to 1 than 0.

III. An important difference between binomial and geometric distributions is that there is a fixed number of trials in a binomial setting but there is not a fixed number of trials in a geometric setting.

A) I only

B) II only

C) III only

D) I and II only

E) I, II, and III

I'm pretty sure the answer is B.
