A baby is added to a hospital nursery. Before the baby was added there were two boys in the nursery and an uncounted number of girls. After the new baby is added a baby is selected at random among all the babies. The selected baby is a boy.
What is the probability that the added baby was a girl?

Ahhh, well there's your problem. If you've got a misconception then you don't end up with anything to add to the hospital nursery no matter how much labour you go through.
