=(5!/4!*3!/2!)-1
=(5*3)-1
=15-1
=14
Answer :- 14
Selected as 5c1*3c1
15
Now A female and B male can be selected frm this only once no..
Ie only one time a and b come together.
So if u minus 15-1..14 times they don't come tgthr
from 3 females if B male taken as a member then A refuses to a member
hence BA can not be a members
5c1*3c1-1
