Answer

\(P(\text{Debit Card}) \approx 28.57\%\)

Steps

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 ：\(P(\text{Debit Card}) \approx 28.57\%\)
