Jack Jokely got up late one morning and was trying to find a clean pair of socks. He has a total of six pairs (3 manroon and 3 white) in his drawer. Jack is not a very good housekeeper and his socks were just thrown in his drawer and, to make the morning perfect, the lightbulb is burned out so he can't see. How many socks does he have to pull out of the drawer before he gets a matched pair (two maroon socks or two white socks)?
