A) With n=11 and p=0.7, find the binomial probability P(4) by using a binomial probability table. B) if np ≥ 5 and nq ≥ 5, also estimate the indicated probability by using the normal distribution as an approximation to the binomial; if np <5 or nq <5, then state the normal approximation cannot be used .
