Henry owns a small business selling clothing. He knows that in the last week 70 customers paid cash, 20 customers used a debit card, and 22 customers used a credit card.

Question

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

Answer 1

To find the probability that the next customer will pay with something other than a debit card, we need to consider the total number of customers who paid with cash or credit card.

Total number of customers who paid with cash or credit card = 70 (cash) + 22 (credit card) = 92

Total number of customers = 70 (cash) + 20 (debit card) + 22 (credit card) = 112

Therefore, the probability that the next customer will pay with something other than a debit card is 92/112, or approximately 0.8214.

Converting this probability to a percentage to the nearest whole number, we get 82%.

So, the probability that the next customer will pay with something other than a debit card is 82%.
