Finding a Matching Pair in Sloppy Joe's Sock Drawer
Sloppy Joe has lots of socks but not all have matching pairs. He has 5 blue socks, 7 red socks, 3 white socks, and 4 green socks. It's early in the morning and dark and he doesn't want to turn on the light and wake his wife. When he randomly picks two socks from the drawer what is the probability that they match? Provide your answer to the nearest tenth of a percent.
