The question is:
The number of car accidents an insured person faces depends on their experience. The rate at which Liam will have car accidents is given by:
$$R(e) = \frac{(e+0.5)^{-2}}{200},$$
where $e$ is the experience in years.
I am required to find probabilities related to this, but the solution starts out with:
The rate at which Liam will have a car accident is a non-homogenous (continuous time) Poisson process.
How is this in any way a Poisson process? Like, what does the function have to do with it? Is this just assumed?
