A couple already has three children. All three children are boys. Assume that the probabilities of the man fathering a boy or a girl are .50 and .50, respectively. What is the probability that the fourth child will also be a boy?

The probability that the fourth child be a boy or a girl doesn't depend on the sex of child born before because the events are independant. So the probability that the fourth child be also a boy is .50
