An owner of a small store knows that in the last week 54 customers paid cash, 42 paid with debit card, and 153 paid with credit card. based on the number of customer from last week, which fraction is closet to the probability that the next customer will pay cash?

The correct answer for the question that is being presented above is this one: :"18/83." First we need to know the total number of customers, so we should add 54+42+153, which equals 249. Now we know that last week, 54 out of 249 total customers paid with cash. As a fraction, 54/249 reduces to 18/83.
