Crystal · Answer 1

20% probability that the next customer will pay with cash

Step-by-step explanation:

A probability, as a decimal, is the number of desired outcomes divided by the number of total outcomes.

To find as percent, we multiply by 100.

In this question:

Total of 54+63+153 = 270 customers.

Of those, 54 paid with cash.

Based on the number of customers from last week, what is the probability as a percent that the next customer will pay with cash?

54/270 = 0.2

0.2*100 = 20%

20% probability that the next customer will pay with cash
