Q1: A craftsman has three identical boxes, each with two identical drawers. In the first box, one drawer contains 6 flange nuts, and the other drawer contains 5 hex bolts. In the second box, one drawer contains 4 flange nuts, and the other drawer contains 6 hex bolts. In the third box, one drawer contains 7 flange nuts, and the other drawer contains 4 hex bolts. 1. If he selects a box at random, opens a drawer at random, and finds a flange nut. What is the probability that box I was selected? 2. If he selects a box at random, opens a drawer at random, and finds a hex bolt. What is the probability that box III was selected?
