Hello,
This is my first post. Please correct me if this is not the right category.
I have tried using the normal formula I know to solve this combination problem, but doesn't give the right answer (which is supposed to be 431).
"A committee of 5 persons is to be formed out of 6 Americans and 5 Russians. In how many ways can this committee be formed if, in the committee, exactly 2 are Americans."
