Question 267144: 18 pairs of socks in a drawer. 8 white pairs, 6 black pairs, 4 blue pairs.

You can put this solution on YOUR website! 18 pairs of socks in a drawer. 8 white pairs, 6 black pairs, 4 blue pairs.
probability of selecting a pair of black on first draw = 6C2/18C2 = 15/153
then P(blue or white on second after 2 black on 1st) = 12/16 = 3/4
