Question

Thirty percent of all customer who enter a store will make a purchase. Suppose that six customers enter the store and that these customers make independent purchase decisions. Let x = the number of the six customer who will make a purchase. Write the binomial formula for this situation. Use the binomial formula to calculate The probability that exactly five customers make a purchase The probability that at least three customers make a purchase The probability that two or fewer customers make a purchase The probability that at least one customer makes a purchase.
