Maths problem 2

I have two children. One is a boy born on a Tuesday. What is the probability I have two boys?

I will rule myself out of this one as I know the answer having just heard it on Radio 4 :)

Unless, of course, your two children are twins. If they are twins, and they are identical, then the probability is 100% since identical twins always are of the same gender. If not, then the probability is 50%. If the children are not twins, the fact that the boy was born on a Tuesday is irrelevant.

Zero. You don't have enough testosterone yourself to father a boy.
