A package contains 12 sweaters, 3 of which are blue. If 4 are selected, find the probability of getting 1 blue sweater
-------------------------
# of ways to pick a blue: 4
# of ways to pick 3 non-blue: 8C3 = (8*7*6)/(1*2*3) = 56
------------------------------------
# of ways to pick 4 without restriction: 12C4 = 495
============================
P(one blue) = [4*56]/495 = 0.4525..
Cheers,
