Question

Aubree owns a small business selling clothing. She knows that in the last week 69 customers paid cash, 2 customers used a debit card, and 7 customers used a credit card.
Based on these results, express the probability that the next customer will pay with something other than cash as a percent to the nearest whole number.

GPT 3.5 · Answer

To find the probability that the next customer will pay with something other than cash, we need to add the number of customers who used a debit card or credit card, which is 2 + 7 = 9.

The total number of customers in the last week is 69 + 2 + 7 = 78.

Therefore, the probability that the next customer will pay with something other than cash is 9/78 = 0.1154.

Converting this probability to a percentage to the nearest whole number, we get 12%.

So, the probability that the next customer will pay with something other than cash as a percent to the nearest whole number is 12%.
