What is the probability that no more than 8 of the entry forms will include an order? Round your answer to four decimal places.Explanation / Answer
no of orders = 12
probability of receiving a magazine subscription order with an entry form is 0.4
probability that no more than 8 of the entry forms will include an order = 1-P(9)-P(10)-P(11)-P(12)
= 1- (12C9)*(0.4)9(0.6)3 - (12C10)(0.4)10(0.6)2 -(12)(0.4)11(0.6)1-(0.4)12
=0.9847
