Question 450920
A committee is to consist of three members. 
If there are seven men and five women available to serve on the committee, how many different committees can be formed?
-----
0 men: 5C3 = 10 committees
---
1 man: 7C1*5C2 = 7*10 = 70 committees
---
2 men: 7C2*5C1 = 21*5 = 105 committees
---
3 men: 7C3 = 35 committees
-----------------------------------------
Total # of committees: 10+70+105+35 = 220
