1. **State the problem:** We need to find the probability that the next customer will pay with cash or a credit card based on past data. 2. **Identify the total number of customers:** Total customers = 122 (cash) + 14 (debit card) + 4 (credit card) = 140. 3. **Calculate the favorable outcomes:** Customers paying with cash or credit card = 122 + 4 = 126. 4. **Write the probability formula:** $$P(\text{cash or credit card}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$$ 5. **Substitute values:** $$P = \frac{126}{140}$$ 6. **Simplify the fraction:** $$\frac{126}{140} = \frac{\cancel{14}9}{\cancel{14}10} = \frac{9}{10}$$ 7. **Convert to decimal:** $$\frac{9}{10} = 0.9$$ 8. **Round to nearest hundredth:** 0.9 is already at the hundredth place. **Final answer:** The probability that the next customer will pay with cash or a credit card is **0.90**.
