At a store, the first 100 customers each randomly choose a coupon from a box, use the coupon, and then replace it. The table shows the number of coupons of each value that are in the box.

Box of Coupons
Discount Value of Coupon
(dollars) Number of Coupons
2 18
5 15
8 11
10 6

What is a reasonable prediction for the number of times an $8 coupon or a $10 coupon will be chosen from the box?

Answer 1

Based on the number of coupons in the box, we can predict that customers will choose an $8 coupon or a $10 coupon approximately 17 times. This prediction is based on the fact that there are a total of 17 $8 and $10 coupons in the box (11 $8 coupons and 6 $10 coupons).
