You can put this solution on YOUR website! If a class has 34 students of which 12 are female and the rest are male.
(a) We wish to form a committee of 6 people from the students. How many distinct committees can be formed?
Ans: 34C6 = 1,344,904
==================================
b) If there is a restriction that the committee has to be 3 male and 3 female. Now how many distinct committees can we form?
# of ways to pick 3 male: 22C3
# of ways to pick 3 female: 12C3
-----
# of ways to pick 3male and 3femaile = 22C3*12C3 = 338,800
================
Cheers,
