Question

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

Answer 1

54+42+153=249   that would be your denominator
54     customers paid by cash      your numerator
so 54/249  is your fraction but you have to simplify that
18/83 would be your final answer

Answer 2

You would add 54+42+153=249 to find the total amount of customers from the previous week. Then you would divide 54/249= 0.2168 to find the amount of customers that used cash to total customers. The closest fraction would be about 1/5.
