Annabelle owns a small business selling clothing. She knows that in the last week 56 customers paid cash, 26 customers used a debit card, and 9 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.
To find the probability that the next customer will pay with a debit card, we need to divide the number of customers who paid with a debit card by the total number of customers who paid in the last week.
Total number of customers = 56 (cash) + 26 (debit) + 9 (credit) = 91
Probability of paying with a debit card = 26/91 ≈ 0.2857
As a percent to the nearest whole number, the probability is 29%.
