I would like to ask how to do this question
The number of cars which pass a roadside speed camera are assumed to behave as a Poisson process with intensity λ. It is found that the probability that a car exceeds the designated speed limit is p.
Show that the number of cars which break the speed limit also form a Poisson process.
If n cars pass the camera in time t, find the probability function for the number of cars which exceed the speed limit.
