Explanation:

Step1: Calculate total number of customers

First, we need to find the total number of customers by adding the number of customers who paid cash, used a debit card, and used a credit card. So, total customers = 49 (cash) + 42 (debit) + 32 (credit).
$$49 + 42 + 32 = 123$$

Step2: Calculate probability of credit card payment

The probability of an event is the number of favorable outcomes (credit card customers) divided by the total number of outcomes (total customers). So, probability = number of credit card customers / total customers.
$$\frac{32}{123} \approx 0.2602$$

Answer:

0.26
