Question

Bella owns a small business selling ice-cream. She knows that in the last week 50 customers paid cash, 2 customers used a debit card, and 4 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

There were 50 + 2 + 4 = 56 customers total. Cash or credit = 50 + 4 = 54, so probability = 54/56 = 27/28 ≈ 0.9642857. Rounded to the nearest hundredth: 0.96.
