In a certain group of 10 members, 4 members teach only French and the rest teach only Spanish or German. If the group is to choose a 3-member committee, which must have at least 1 member who teaches French, how many different committees can be chosen?

a) 40
b) 50
c) 64
d) 80
e) 100

I was stumped with this one. Please explain you answer?!

There cases:

case 1: 1 french teacher
4C1* 6C2 = 60

case 2: 2 french teacher
4C2* 6C1 = 36

case 3: 3 french teacher
4C3 = 4

Answer: 100
