# Question: In this problem we generalize the results of Exercise Suppose

In this problem, we generalize the results of Exercise. Suppose a discrete random variable takes on nonnegative integer values and has a CDF of the general form

(a)What conditions must the sequence ak satisfy for this to be a valid CDF.

(b) For a positive integer n, find Pr (X ≤ n) in terms of the ak.
