  1. A sex-linked gene is on the X chromosome, and XX makes a girl. The daughter, getting the hemophilia gene from dad, is a carrier.

    Since her husband can only give a normal X chromosome, the most her daughters could be is carriers, but by chance, half of the boys will have hemophilia.

    Probability of all events occurring is found by multiplying the probability of the individual events.
