Jim's sock drawer has two pairs of black socks, three pairs of white, one pair of green, and two pairs of gray. One evening he randomly picks three socks assuming that he will get a matched pair, but instead turns up with 1 black, 1 white, and 1 gray sock. Without putting back the socks he picked, he picks another sock randomly. What is the probability that he will have a complete pair?
