uestion: 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!(482)!= 48X47/2 = 24X47=1128
C(52,5) = 2598960
P(3KINGS) = 47 / 108290
Correct?

Correct!
