The probability is (Round to four decimal places as needed.) b. What is the probability that less than 3 people will make a purchase? The probability is (Round to four decimal places as needed.) c. What is the probability that more than 1 person will make a purchase? The probability is (Round to four decimal places as needed.) d. Suppose that out of the 15 customers, 6 made a purchase.
