If np 5 and nq5, estimate P(morethan8) with n=12 and p=0.4 by using the normal distribution as an approximation to the binomial distribution; if np<5 or nq<5,

then state that the normal approximation is not suitable.

P(more than 8)=__________________=

(Round to four decimal places as needed.)

or

B.The normal distribution cannot be used
