A small company employs 3 men and 5 women. If a team of 4 employees is to be randomly selected to organize the company retreat, what is the probability that the team will have exactly 2 women?

1/14
1/7
2/7
3/7
1/2

Any formula to solve this type of question?

I was thinking:

5C2 X 3C2
----------
8C4

but, its wrong


D
