Question

Fatoumata owns a small business selling ice-cream. She knows that in the last week 13 customers paid cash, 39 customers used a debit card, and 5 customers used a credit card.
Based on these results, express the probability that the next customer will pay with a debit card as a percent to the nearest whole number.

Answer 1

Total customers = 13 + 39 + 5 = 57.
Probability (debit) = 39/57 = 13/19 ≈ 0.68421 = 68.421% ≈ 68%.

So the probability is 68%.
