Sofia owns a small business selling ice-cream. She knows that in the last week 56 customers paid cash, 6 customers used a debit card, and 18 customers used a credit card. Based on these results, express the probability that the next customer will pay with a credit card as a fraction in simplest form.

9/40

Step-by-step explanation:

1) add the amount of the customers together:

56+6+18=80

80 will be your denominator

2) look at the amount that paid with a credit card, which is 18, and that will be your numerator:

18/80

3) simply it, which 18/80 simplified is 9/40

hence, the probability is 9/40 that the next customer will pay with a credit card.
