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?

r we assuming that when the boy was picked out of the group it was following the majority? cause it could just be pure dumb luck that a boy was picked
