Answer:
85%
Step-by-step explanation:
The probability of finding our satisfactory service in the three visits in a row would be the multiplication of the probability of each event.
The event is always the same. 95% of the service will be satisfactory. That is a probability of 95/100
Then the final probability would be:
(95/100) * (95/100) * (95/100) = 0.85
In other words, the probability that a customer who visits three times will find our service satisfactory is 85%
