question\ndaniel owns a small business selling used books. he knows that in the last week 60 customers paid cash, 4 customers used a debit card, and 23 customers used a credit card.\nbased on these results, express the probability that the next customer will pay with a credit card as a fraction in simplest form.\nanswer attempt 1 out of 2

Answer

Explanation:

Step1: Calculate total number of customers

$60 + 4+23=87$

Step2: Calculate probability of paying with credit - card

The number of customers who used a credit card is 23. The probability $P$ that the next customer will pay with a credit card is the number of customers who used a credit card divided by the total number of customers. So $P=\frac{23}{87}$. Since 23 is a prime number and 23 and 87 have no common factors other than 1, the fraction is already in simplest form.

Answer:

$\frac{23}{87}$
