A box has 17 candies in it: 5 are taffy, 4 are caramel, and 8

are butterscotch. (Each candy falls into only one of these categories.) Debra wants to select two candies to eat for dessert. The first candy will be selected at random, and then the second candy will be selected at random from the remaining candies. What is the probability that the two candies selected are taffy?

Do not round your intermediate computations. Round your final answer to three decimal places.
