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:
$68%$
