A committee consisting of 3 men and 3 women is to be formed.
(a) 2 of the men refuse to serve together.
Number of men who don't want to serve together = 2
Remaining men = 4
Total ways = Both men who don't want to serve together are not selected + only one of them is selected.


(b) 2 of the women refuse to serve together.
Number of women who don't want to serve together = 2
Remaining men = 6

(c)1 man and 1 woman refuse to serve together.
Ways = Total ways - Both man and woman are select who refuse the serve together


Hi there!
3c + 2d = 2 for d = 4
3c + 2(4) = 2
3c + 8 = 2
Subtract 8 to both sides
3c + 8 - 8 = 2 - 8
3c = -6
Divide both sides by 3
3c/3 = -6/3
c = -2
I hope I helped!
