Green cards

We draw 4 cards from a deck of 32 cards. In how many ways can we draw:
a) exactly 2 aces,
b) exactly 3 green cards?

Final Answer:

a =  2268
b =  1344

Step-by-step explanation:

C2(28)=(228)=2!(282)!28!=212827=378 C2(4)=(24)=2!(42)!4!=2143=6  a=(24) (2324)=6 (2324)=2268
C1(24)=(124)=1!(241)!24!=124=24 C3(8)=(38)=3!(83)!8!=321876=56  b=(38) (1328)=56 (1328)=1344
