A family has seven children. If this family has exactly two boys, how many different birth and gender orders are possible?
There are _____. different birth and gender orders possible.
This is the combination problem .
n C x = n! / x!(n - x)!
n! = n(n - 1)(n - 2) .... and so on .
n = 7 and x = 2
7 C 2 = 7! / 2!(7 - 2)! = 7! / 2!(5)! = 21
There are 21 different birth and gender orders possible.
