You can put this solution on YOUR website! A committe of 4 is to be chosen from a group of 6 boys and 5 girls
---------------------------------------------
my question is what is the probability that a committee consists of:
exactly two boys and two girls,:::[6C2*5C2]/11C4
------
have at least one girl on it::: 1-[6C4/11C4] = 0.9545
------
have at least one girl and at least one boy on it
-------
have at most one girl on it?:::[6C4+6C3*5C1]/11C4
