Question

Omar owns a small business selling used books. He knows that in the last week 102 customers paid cash, 22 customers used a debit card, and 10 customers used a credit card.

Based on these results, express the probability that the next customer will pay with something other than cash as a percent to the nearest whole number.

Answer 1

The probability that the next customer will pay with something other than cash as a percent to the nearest whole number is 24%.

What is Probability?

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

Given that,

Number of customers who paid cash = 102

Number of customers who used a debit card = 22

Number of customers who used a credit card = 10

Total number of customers = 102 + 22 + 10 = 134

Total customers who don't use cash to pay = 22 + 10 = 32

Probability that the next customer doesn't pay cash = 32 / 134

= 0.2388

= 23.88%

≈ 24%

So let us conclude that 24% of probability is that the next customer will pay with something other than cash.
