Question

Jocelyn owns a small business selling used books. She knows that in the last week, 63 customers paid cash, 2 customers used a debit card, and 2 customers used a credit card. Based on these results, express the probability that the next customer will pay with cash as a decimal to the nearest hundredth.

Answer 1

The probability that the next customer will pay with cash at Jocelyn's bookstore is calculated by dividing the number of cash customers (63) by the total number of customers (67), resulting in a probability of 0.94 when rounded to the nearest hundredth. Therefore, the probability that the next customer will pay with cash is 0.94.

Step-by-step explanation:

The question asks us to calculate the probability that the next customer will pay with cash at Jocelyn's book store. To find this probability, we'll use the information provided about past customer payments. Jocelyn owns a small business selling used books, and the payment methods for the last week were 63 customers with cash, 2 with debit cards, and 2 with credit cards.

The total number of customers is 63 (cash) + 2 (debit card) + 2 (credit card) = 67 customers.

To find the probability of a cash payment by the next customer:

• Divide the number of cash payments by the total number of transactions.
• P(cash) = 63 (cash customers) / 67 (total customers)
• P(cash) = 0.94 (to two decimal places)

Therefore, the probability that the next customer will pay with cash is 0.94.
