As a marketing promotion a company is going to give the first 200 customers a coupon for a discount when they enter the store. The customer cannot scratch off the coupon until they check out. the company orders 200 coupons and 150 are for 5% off, 30 are for 10% off, 15 are for 25% off, 4 are for 50% off and 1 is for 75% off. What is the probability that the first person who receives a coupon gets one for a discount of 25% off?

15/200 = ?

To find the probability that the first person who receives a coupon gets one for a discount of 25% off, we need to calculate the ratio of the number of coupons for a 25% discount to the total number of coupons.

Let's break down the number of coupons:

- 150 coupons are for a 5% discount.
- 30 coupons are for a 10% discount.
- 15 coupons are for a 25% discount.
- 4 coupons are for a 50% discount.
- 1 coupon is for a 75% discount.

The total number of coupons is the sum of these numbers:
150 + 30 + 15 + 4 + 1 = 200

To calculate the probability, we divide the number of coupons for a 25% discount (15) by the total number of coupons (200):

15 / 200 = 0.075

Therefore, the probability that the first person who receives a coupon gets one for a discount of 25% off is 0.075 or 7.5%.
