You are in a pitch black room and need to get a pair of socks out of your drawer which can contain up to 100 socks. In the drawer is a mixture of black and white socks, and there's at least one pair of either color. If you choose two socks, the chance that you draw out a black pair is 2/3.
What is the chance that you draw out a white pair?
______________________________________________
Bonus: what would the answer be if the drawer contained between 100 and 1000 socks?

That's good thinking except that the problem requires that "there's at least one pair of either color". And your solution has only one white sock.
