What is Poisson Distribution

The concept of probability distribution is one of the most relevant but, in some ways, among the most complex concepts to be treated at school. If we exclude some fairly simple cases, there is a variety of distributions whose formulation and use is not trivial. In this chapter, many distributions have been omitted (e.g., exponential, t student, Weibull, etc.) because they are too specialized and reserved for a higher level of study. The choice has privileged distributions that can be analyzed starting from objects with which students are, or maybe, familiar. However, the distributions addressed are sufficient to give a fairly broad idea of the topic.
