Question

Aaden owns a small business selling used books. He knows that in the last week 87 customers paid cash, 5 customers used a debit card, and 24 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.

Answer 1

There were 87 cash payments out of 87 + 5 + 24 = 116 customers, so the estimated probability is 87/116 = 3/4 = 0.75 = 75%.
