A family plans to have three children. The wife and husband are trying to determine the probabilities of the different gender outcomes for the children.

The husband thinks that the probability that the first child is a girl is greater than the probability that the first child is a girl and the second child is a girl. The wife disagrees. She thinks that the two probabilities are equal.

The sample space of possible outcomes is listed below. B represents a boy, and G represents a girl.
