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.
Answer
Attempt 1 out of 3
To find the probability that the next customer will pay with a debit card or a credit card, we need to add the number of customers who paid with a debit card and the number of customers who paid with a credit card, and then divide by the total number of customers.
Number of customers paying with debit card = 30
Number of customers paying with credit card = 96
Total number of customers = 5 (cash) + 30 (debit) + 96 (credit) = 131
Probability of paying with debit card or credit card = (30 + 96) / 131 = 126 / 131 ≈ 0.9618
Converting into a percentage 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%.
