a) prob = C(13,3) * C(13,2)/C(52,5)
= 286*78/2598960
= 286/33320
= 11/99960
b) prob = C(4,2) * C(4,2)* C(44,1)/C(52,5)
= 6*6*44/2598960
= 3*11/54145
= 33/54145

is C for nCr???? i'm a little confused
yes
C(n,r) = nCr
its an easier notation to type
C(n,r) = nCr
its an easier notation to type
Ohhhhhhh! okay, thank you! :)
Wait, how'd you get 33320 in A?
2598960/78 = 33320
