Question
A fair provides a shuttle bus from a parking lot to the fair entrance. Buses arrive at the parking lot every 10 minutes. They wait for 4 minutes while passengers get on and get off. Then the buses depart.
What is the probability that there is not a bus waiting when a passenger arrives at a random time?
Hint:
The correct answer is:
The question asks us to find the probability that there is not a bus waiting when a passenger arrives at a random time
Probability = 
=
=
Therefore the probability that there is not a bus waiting when a passenger arrives at random time is 3/5
