If the psychic guesses right he or she is going to keep all the money. But if psychic does not guess right he or she promises to give the $60 back and pay in addition $20 out of her pocket as a compensation for the wrong answer. Assume postage fees for the return mail are $1. Also assume that the probability of having a boy is 51% and the probability of having a girl is 0.49%. Suppose that the psychic simply replies \"girl\" to all inquiries. Assume that everyone who has a boy will ask for her money back.
