If you are lucky you only have to pull 2 socks out, you have 2 black or white socks. Or you have one of each, so on your third pull you will have a matching pair of socks. On you third pull you will have 2 black socks or 2 white socks. no one can dispute this answer it is mathematically correct. It took a thousand times longer to type the answer than it did for me to have the answer.

Three. b/c let's say you the first pick you get a black sock. The second pick you get a white sock. On your third try, you have to get either a black or white sock. Therefore you get a matching pair. :]
