Question

Alexandra owns a small business selling bagels. She knows that in the last week 95 customers paid cash, 4 customers used a debit card, and 31 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 fraction in simplest form.

Answer 1

last week

(dc: debit card & cc: credit card)

# of customers paid cash: 95
# of customers paid with dc: 4
# of customers paid with cc: 31

95+4+31= 130

Something other than a cc, meaning we sum the values of the # of customers who paid cash or dc.

= 99

Answer: 99/130
