If my dresser has 10 black socks and 12 blue socks and I randomly pull out two socks, what are the chances that they are both blue?

Answer 1

22 total socks, 12 blue, so 1st time, have 12/22 = 6/11 probability of getting blue sock

Now 21 total socks, 11 blue, so 2nd time, 11/21 probability of getting blue sock

Probability of both occurring = 6/11 * 11/21 = 6/21 = 2/7
