Hawa owns a small business selling clothing. She knows that in the last week 5 customers paid cash, 30 customers used a debit card, and 96 customers used a credit card.

Question

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

Answer 1

The total number of customers in the last week was 5 (cash) + 30 (debit card) + 96 (credit card) = 131.

The probability that the next customer will pay with a debit card or a credit card is equal to the number of customers who used debit card or credit card divided by the total number of customers:

(30 + 96) / 131 = 126 / 131 ≈ 0.9618

Convert this probability to a percent to the nearest whole number:

0.9618 * 100 ≈ 96%

Therefore, the probability that the next customer will pay with a debit card or a credit card is approximately 96%.
