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.
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%.
