Q. Camila owns a small business selling used books. She knows that in the last week 4040 customers paid cash, 1616 customers used a debit card, and 3939 customers used a credit card. Based on these results, express the probability that the next customer will pay with a credit card as a decimal to the nearest hundredth.
  1. Calculate Total Customers: Calculate the total number of customers.\newlineTotal customers = 4040 (cash) + 1616 (debit card) + 3939 (credit card)\newlineTotal customers = 9595
  2. Calculate Probability: Calculate the probability of a customer paying with a credit card.\newlineProbability = Number of customers who used a credit cardTotal number of customers\frac{\text{Number of customers who used a credit card}}{\text{Total number of customers}}\newlineProbability = 3995\frac{39}{95}
  3. Convert to Decimal: Convert the probability to a decimal.\newlineDecimal probability = 3995≈0.4105\frac{39}{95} \approx 0.4105
  4. Round Probability: Round the decimal to the nearest hundredth.\newlineRounded probability = 0.410.41
