 Pairs of Socks (Posted on 2004-09-01)
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?

Do you think SilverKnight meant to put "each color" or did he deliberately put "each color" to trick us?

I can't find another solution to part 1.

441 black and 99 white seems to fit part 2.
