Question

Violet owns a small business selling clothing. She knows that in the last week 53 customers paid cash, 3 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 or a credit card as a decimal to the nearest hundredth.

Answer 1

The total number of customers in the last week is 53 + 3 + 2 = 58.
The probability that the next customer will pay with cash or a credit card is (53 + 2)/58 = 55/58.

Expressing this as a decimal to the nearest hundredth, we get 0.95. Therefore, the probability is 0.95 that the next customer will pay with cash or a credit card.
