Read Solution (Total 5)
-
- Total cards=52
choosing 3 cards=52C3
choosing one spade=13C1
choosing one red queen=2C1
choosing one black queen=2C1
so answer is,
(13C1*2C1*2C1)/52C3

- i think there sholud be two cases one where the spade drawn is not a black king and other where it is.
so it may be..
12/52*2/51*2/50+1/52*2/51*1/50
