Question

Enola owns a small business selling ice-cream. She knows that in the last week 25 customers paid cash, 76 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 a credit card as a decimal to the nearest hundredth.

Answer 1

So the probability that the next customer will pay with something other than a credit card is approximately 0.91 to the nearest hundredth.

Explanation:

To find the probability that the next customer will pay with something other than a credit card, we need to know the total number of customers that Enola had in the last week.

The total number of customers is:

25 (cash) + 76 (debit) + 10 (credit) = 111

So in the last week, Enola had 111 customers in total.

The probability that the next customer will pay with something other than a credit card is:

(25 + 76)/111 = 101/111

To express this as a decimal to the nearest hundredth, we can divide 101 by 111:

101 ÷ 111 ≈ 0.91

Answer 2

So the probability that the next customer will pay with something other than a credit card is approximately 0.91 to the nearest hundredth.

Explanation:

To find the probability that the next customer will pay with something other than a credit card, we need to know the total number of customers that Enola had in the last week.

The total number of customers is:

25 (cash) + 76 (debit) + 10 (credit) = 111

So in the last week, Enola had 111 customers in total.

The probability that the next customer will pay with something other than a credit card is:

(25 + 76)/111 = 101/111

To express this as a decimal to the nearest hundredth, we can divide 101 by 111:

101 ÷ 111 ≈ 0.91
