during a special promotion, each customer who makes a purchase is given a coupon for a discount of either 10,20, 30,40, or 50 percent. if a customer has an equal chance of receiving any one of the 5 types of discount coupons,what is the probability that the first customer will receive a discount coupon for less than 25 percent?

p of any single value = 1/5 = .20

p of 10 = .20
p of 20 = .20

p of 10 or 20 = .40

To find the probability that the first customer will receive a discount coupon for less than 25 percent, we need to calculate the ratio of favorable outcomes to total possible outcomes.

In this case, the favorable outcomes are the discount coupons for less than 25 percent, which are the 10 percent and 20 percent coupons. There are two favorable outcomes.

The total possible outcomes are the five types of discount coupons, which are 10 percent, 20 percent, 30 percent, 40 percent, and 50 percent. There are five total possible outcomes.

To calculate the probability, we divide the number of favorable outcomes by the total number of possible outcomes:

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = 2 / 5

So the probability that the first customer will receive a discount coupon for less than 25 percent is 2/5 or 0.4.
