Problem
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.
Solution
Step 1 ：\(P(\text{Debit Card}) = \frac{\text{Number of Debit Card Customers}}{\text{Total Customers}}\)
Step 2 ：\(P(\text{Debit Card}) = \frac{26}{56+26+9}\)
Step 3 ：\(P(\text{Debit Card}) = \frac{26}{91} \approx 0.2857\)
Step 4 ：\(P(\text{Debit Card}) \approx 28.57\%\)
