Choc chip -- 12
oatmeal ---- 12
no-bake ---- 12
peanut butter --12
gingerbread ---12
Sample space = C(60,6)
selections of six gingerbread from 12 = C(12,6)
prob = C(12,6)/(C(60,6) = .000018456
If you make a bunch of cookies, and ten of your friends wanted some cookies. There are, in total, 5 dozen (60) cookies. Each dozen is a different kind; chocolate chip, oatmeal, no-bake, peanutbutter, and gingerbread. If you put all 60 cookies in a tin, which I wouldn't advice doing, and pick six cookies to give to one friend, what is the probability of you picking all all gingerbread cookies?
