The probability that the next customer will pay with a credit card is 0.26.

Explicar

## Step 1<br />First, we need to calculate the total number of customers. This is done by adding the number of customers who paid with cash, debit card, and credit card. <br /><br />### \(49 + 42 + 32 = 123\)<br /><br />## Step 2<br />Next, we calculate the probability of a customer paying with a credit card. This is done by dividing the number of customers who paid with a credit card by the total number of customers.<br /><br />### \(P(\text{credit card}) = \frac{32}{123}\)<br /><br />## Step 3<br />Finally, we convert this probability to a decimal and round it to the nearest hundredth.<br /><br />### \(P(\text{credit card}) = 0.26016\)<br /><br />Rounding this to the nearest hundredth gives us 0.26.
