Homework Help: probabilities

Posted by marco on Friday, March 4, 2011 at 3:16pm.

Question: Five cards are dealt from standard deck of 52 cards, what is the probability of being dealt 3 kings?

Here is what I have

P(3 kings)=

C(4,3) = 3 out of 4 kings being dealt
C(48,2 = 2 out of remaning cards to complete 5 card deal

C(52,5) = 5 cards dealt out of 52 card deck.

C(4,3) = 4

C(48,2) = 48!
2!(48-2)!= 48X47/2 = 24X47=1128

C(52,5) = 2598960

P(3KINGS) = 47 / 108290

Correct?
