Question

Violet owns a small business selling used books. She knows that in the last week 69 customers paid cash, 34 customers used a debit card, and 11 customers used a credit card.

Based on these results, express the probability that the next customer will pay with cash or a credit card as a percent to the nearest whole number.

Answer 1

70 percent.

Explanation:

To calculate the probability that the next customer will pay with cash or a credit card, we need to add the number of customers who paid with cash (69) to the number of customers who paid with a credit card (11):

69 + 11 = 80

So out of the total number of customers, 80 paid with cash or a credit card. To express this as a percentage to the nearest whole number, we need to divide 80 by the total number of customers (69 + 34 + 11 = 114) and then multiply by 100:

(80 / 114) x 100 ≈ 70

Therefore, the probability that the next customer will pay with cash or a credit card is approximately 70 percent.
