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

Using Normal Approximation. In Exercises 5–8, do the following: If the requirements of np Ú 5 and nq Ú 5 are both satisfied, estimate the indicated probability by using the normal distribution as an approximation to the binomial distribution; if np 6 5 or nq 6 5, then state that the normal approximation should not be used.
