There were a total of 134 customers in the last week (102 cash, 22 debit, and 10 credit).
The probability that the next customer will pay with something other than cash is:
(22 debit customers + 10 credit customers) / 134 total customers = 32 / 134
Convert this fraction to a percentage:
(32 / 134) * 100 = 23.88%
Rounded to the nearest whole number, the probability that the next customer will pay with something other than cash is 24%.
