A box has 17 candies in it: 5 are caramel, 4 are taffy, and 8 are peppermint. (Each candy falls into only one of these categories.) Jim 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 peppermint? Do not round your intermediate computations. Round your final answer to three decimal places.
