I think it was in how many ways can the man or the women be on the committee but not both
$!$RatJumper$!$:
As far as i remember, the info they gave was:
If there are 10 men and 9 women. What are the ways of choosing 6 people if there are atleast 4 men and 1 woman.
iii) If one particular man or one particular women are on the committee but not both.
Answer I got:
(9C3*8C1*13C1) + (9C3*8C2) + (9C4*8C1) + (8C1*9C4) + (8C0*9C5) = 13230
