Do it like the other question I just showed you.
This time I see 3 cases:
1. one Democrat
2. two Democrats
3. three Democrats
I'll do #2
no. of selections = C(6,2) * C(8,5) = 15*56 = 840
Assume that the committee consists of 8 Republicans and 6 Democrats. A subcommittee consisting of 7 people is to be selected. How many such subcommittees are possible if each subcommittee must contain at least 1 and no more than 3 Democrats?
