With n = 8 births and p = 0.512 for a boy, find P(exactly 5 boys).

Do the following: If the requirements of np ≥ 5 and nq ≥ 5 are both satisfied, estimate the indicated probability by using the normal distribution as an approximation to the binomial distribution; if np < 5 or nq < 5, then state that the normal approximation should not be used.
