The probability that the next customer will pay with a credit card is 0.26.
Explicación
## Step 1First, 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. ###
## Step 2Next, 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.### \(P(\text{credit card}) = \frac{32}{123}\)## Step 3Finally, we convert this probability to a decimal and round it to the nearest hundredth.### \(P(\text{credit card}) = 0.26016\)Rounding this to the nearest hundredth gives us 0.26.
