At the first tricity meeting, there are 8 people from town A, 7 people from town B, and 5 people from town C. If a council consisting of 5 people is randomly selected, find the probability that 3 are from town A and 2 are from town B. I know this is a combination but I am having a hard time figuring out the answer.

[(8 combination 3)(7 combination 2)(5 combination 0)] divided by (20 combination 5)
= .0758513932
