(p. 165). Recall that the rankings were based on the results of an online contest in which participants were asked which of two different Halloween candies they prefer. The two candies compared were randomly selected from 86 different candy varieties. All four Reese’s products were ranked among the top ten: Reese’s Peanut Butter Cup (ranked #1), Reese’s Miniatures (#2), Reese’s Pieces (#6), and Reese’s Stuffed with Pieces (#8).

a. In Exercise 3.23c, you computed the probability that the two candies selected for comparison are both Reese’s products. Show how to use the hypergeometric probability distribution to compute this probability.

b. Find the probability that of the two candies selected for comparison, only one is a Reese’s product.
