Part 1

You meet a man in a bar who tells you that he has two children. He tells you that one of his children is a girl (now, she does have a name, but he doesn't mention it).

What is the probability that his other child is also a girl? (Hint: It's not 1/2)

Part 2

You meet a man in a bar who tells you that he has two children. He tells you that one of the children is a girl, and her name is Debra.

What is the probability that his other child is also a girl? (Hint: it's not the same answer as the part one)
