Q. Bentley owns a small business selling bagels. He knows that in the last week 5555 customers paid cash, 1111 customers used a debit card, and 6565 customers used a credit card.\newlineBased on these results, express the probability that the next customer will pay with cash as a percent to the nearest whole number.\newlineAnswer:
  1. Calculate total number of customers: Calculate the total number of customers by adding the number of customers who paid with cash, debit card, and credit card.\newlineTotal number of customers == Number of customers who paid cash ++ Number of customers who used a debit card ++ Number of customers who used a credit card\newlineTotal number of customers =55= 55 (cash) +11+ 11 (debit card) +65+ 65 (credit card)\newlineTotal number of customers =131= 131
  2. Calculate probability for cash payment: Calculate the probability that the next customer will pay with cash. The probability is the number of customers who paid with cash divided by the total number of customers.\newlineProbability (cash) = Number of customers who paid cashTotal number of customers\frac{\text{Number of customers who paid cash}}{\text{Total number of customers}}\newlineProbability (cash) = 55131\frac{55}{131}
  3. Convert probability to percent: Convert the probability to a percent. To convert a decimal to a percent, multiply by 100100 and round to the nearest whole number.\newlineProbability (cash) as a percent = (Probability (cash) * 100100)%\newlineProbability (cash) as a percent = (55131\frac{55}{131} * 100100)%\newlineProbability (cash) as a percent 41.9847328244\approx 41.9847328244%\newlineRounded to the nearest whole number, the probability is approximately *00%.
