Jacob owns a small business selling bagels. He knows that in the last week 108 customers paid cash, 24 customers used a debit card, and 18 customers used a credit card.

Question

Based on these results, express the probability that the next customer will pay with a debit card or a credit card as a decimal to the nearest hundredth.

Answer
Attempt 1 out of 3

Answer 1

First, we need to calculate the total number of customers in the last week:

108 customers paid cash + 24 customers used a debit card + 18 customers used a credit card = 150 total customers

Next, we need to calculate the probability of the next customer paying with a debit card or a credit card:

(24 customers with debit card + 18 customers with credit card) / 150 total customers = 42 / 150 = 0.28

Therefore, the probability that the next customer will pay with a debit card or a credit card is 0.28 to the nearest hundredth.
