A cooler contains 7 cans of cola: 6 regular colas and 4 diet colas. If 3 cans of cola are selected at random, what is the probability that 2 cans of regular cola and 1 can of diet cola are selected?

Sorry, I meant to say 10 cans NOT 7.

That would equal the probability of getting one diet cola only, on the first, second or third selection.
3 * (4/10)*(6/9)*(5/8) = 1/2
