Mia owns a small business selling bagels. She knows that in the last week 85 customers paid cash, 5 customers used a debit card, and 16 customers used a credit card.
Based on these results, express the probability that the next customer will pay with cash as a percent to the nearest whole number.
The total number of customers in the last week was:
85 + 5 + 16 = 106
The probability that the next customer will pay with cash is:
85/106 = 0.8019
To convert this to a percentage, we multiply by 100:
0.8019 x 100 = 80.19
Rounding to the nearest whole number, we get a probability of 80%. Therefore, the answer is 80%.
