Okay let's try this again...

Four possible combinations of children. Right? That's simple math too, you have two inputs, four outputs.

A girl answers the door... This is GIVEN.

We've now determined that it is impossible for the family to have a boy/boy combination.

Since a girl answering the door is GIVEN, it leaves us with three possibilities.

Two of those possibilites have boys. One possibility has a second girl.


I don't know how else to go aboot this, but I for one am going to trust my OAC finite before I trust logic that I feel is flawed.
