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.
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.
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%.
