For a particular clothing store, a marketing firm finds that 16% of $10 off coupons delivered by mail are redeemed. Suppose six customers are randomly selected and are mailed $10 off coupons. Refer to exhibit 5-9. What is the probability that no more than one of the customers redeems the coupon?
Answer:
P(redeem) = 0.16
probability that no more than one of the customers redeems the coupon = P(0 redeem) + P(1 redeem)
= 6C0 * 0.160 * 0.846 + 6C1 * 0.161 * 0.845
= 0.75278
