We will have two types of families:
1) Those who get a boy first (stop at 1 boy)
2) Those who get a girl first, then stop at the 1st boy after that
Assuming a 50/50 chance of getting a boy in the first place, we must assume that 50% of all the families will just have one boy.
The other 50% will have 1+ girls and a boy
I don't see how the number
