- hi,
-
- can anyone point out what is wrong with my calculation of getting a hand
- of two pairs from a shuffled deck of cards?
-
- the probability i have is:
-
- (13 * 4C2) (12 * 4C2) (4 * 11)
- ------------------------------ = 0.095078
- 52C5
-
- which is exactly two times the correct value (0.047539).
