If np is greater or equal to 5, and np is greater or equal to 5, estimate P(more than 7) with n=12 and p=0.7 by using the normal distribution as an approximation to the binomial distribution, if np is greater 5 or nq is greater than 5, state that the normal approximation is not suitable. P(more than 7) = ____. or the normal distribution cannot be used.
