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?

Have you considered a "mixed pair" in you maths?
My Mistake, misread your comment, sorry
(apology to Nosher)
