    This is a discussion of the puzzle Mom’s Talk, posted in the Brain Teasers section of the website.

    ——————————–

    Two moms, Sarah and Courtney, are talking to each other.

    Sarah: I have two children.
    What is the probability that both of Sarah’s children are boys?

    Courtney: Me too! Do you have any boys?
    What is the probability that both of Courtney’s children are boys?

    Sarah: Yes, I do! What is your younger child?
    What is the probability that both of Sarah’s children are boys?

    Courtney: It is a boy. He is so mischievous!
    What is the probability that both of Courtney’s children are boys?

    Sarah: Is he Sagittarius? Sagittarius boys are known to drive their mothers crazy. I can also testify from personal experience.
    What is the probability that both of Sarah’s children are boys?

    Courtney: No, but actually I have the opposite personal experience to yours.
    What is the probability that both of Courtney’s children are boys?

    Sarah: Well, I guess astrology does not always get it right.

    Courtney: Well, I guess it does about half of the time.
