The Poisson distribution models the number of events occurring within a fixed interval of time or space, given that these events happen with a known constant mean rate and are independent of the time since the last event. In the context of an insurance company, the weekly number of claims can be represented by a Poisson random variable, where the parameter λ (lambda) indicates the average number of claims received per week. This distribution is particularly useful for predicting the likelihood of various claim counts, allowing the company to manage risk and set appropriate premiums.
The Poisson distribution is discrete.
Poisson and Binomial both the distribution are used for defining discrete events.You can tell that Poisson distribution is a subset of Binomial distribution. Binomial is the most preliminary distribution to encounter probability and statistical problems. On the other hand when any event occurs with a fixed time interval and having a fixed average rate then it is Poisson distribution.

Why belong exponential family for poisson distribution
If a random variable X has a Poisson distribution with parameter l, then the probability that X takes the value x isPr(X = x) = lx*e-l/x! for x = 0, 1, 2, 3, ...
A poisson process is a non-deterministic process where events occur continuously and independently of each other. An example of a poisson process is the radioactive decay of radionuclides. A poisson distribution is a discrete probability distribution that represents the probability of events (having a poisson process) occurring in a certain period of time.
