question\nfatoumata owns a small business selling ice - cream. she knows that in the last week 13 customers paid cash, 39 customers used a debit card, and 5 customers used a credit card.\nbased on these results, express the probability that the next customer will pay with a debit card as a percent to the nearest whole number.

Answer

Explanation:

Step1: Calculate total number of customers

$13 + 39+5=57$

Step2: Calculate probability of paying with debit - card

The probability $P$ of a customer paying with a debit card is the number of customers who used a debit card divided by the total number of customers. So $P=\frac{39}{57}$.

Step3: Convert probability to percentage

$P=\frac{39}{57}\times100%\approx 68%$

Answer:

$68%$
