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.
The total number of customers in the last week is 13 + 39 + 5 = 57 customers.
The probability of the next customer paying with a debit card is 39/57.
To express this probability as a percent, we multiply by 100:
(39/57) x 100 = 68.4
So the probability that the next customer will pay with a debit card as a percent to the nearest whole number is 68%.
