○.71
○.72
○.73
○ option 3

Explanation:

Step1: Calculate total customers

First, 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, \(19 + 25 + 24 = 68\) total customers.

Step2: Calculate debit or credit customers

Next, find the number of customers who used a debit card or a credit card. Add the number of debit card customers and credit card customers: \(25 + 24 = 49\).

Step3: Calculate probability

Then, calculate the probability by dividing the number of debit or credit customers by the total number of customers. So, the probability is \(\frac{49}{68} \approx 0.72\) (rounded to the nearest hundredth).
