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.\nanswer attempt 1 out of 2

Answer

Explanation:

Step1: Calculate total customers

$13 + 39+5=57$

Step2: Calculate probability of debit - card payment

The probability $P$ that a customer pays with a debit card is the number of customers who used a debit card divided by the total number of customers. So $P=\frac{39}{57}\approx0.6842$.

Step3: Convert to percentage

To convert the decimal to a percentage, multiply by 100. So $0.6842\times100 = 68.42%$.

Step4: Round to nearest whole number

Rounding $68.42%$ to the nearest whole number gives $68%$.

Answer:

$68%$
