I have a similar question with socks:

10 white, 6 black, how many drawn for one pair of white socks?

**Reiny**, Friday, June 25, 2010 at 7:16amI will do the socks one ...

number of possible pairs = C(16,2) = 120

number of possible white pairs = C(10,2) = 45

so prob that both are white = 45/120 = 3/8

3 : 8 = 1 : 2.6667

Unless my thinking is way off, appr every third pair (I rounded it off) chosen would be a white pair.
