Question

With n = 25 and p = 0.4, find P(more than 9).
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.
