Answer:

Step-by-step explanation:
We need to find the probability that the mechanic will service or more cars.
It's a simpler one given that we have the probabilities of servicing 4 or less cars.
P(at least 5 cars) is given by subtracting the probabilities of servicing both 3 and 4 cars.

The answer is 2 pounds for $1 because you divide 4 by 2 then divide 2 by 2 so 2 pounds for $1.
