Let's Hear it for the Boys

The Puzzler

RAY: Here’s the first half of the puzzler: If a mother has two kids and the older one is a boy, what are the chances the younger is a boy?

TOM: I know this puzzler. This is a killer.

RAY: And the answer is 50-50. So I'll give you that part. Now, suppose a different mother has two kids and one of them is a boy. What are the chances that the other one is a boy? Well, it's got to be 50-50, right?

TOM: You would think.

RAY: Wrong.

TOM: Of course.

RAY: So, what are those chances?
