The link between Poisson and Exponential distribution

When you are dealing with random experiments, linked to a set of possible outcomes, it is useful to assign to each of the possible outcomes (which might be not numerical, like events) a real number, so that you can make useful computations.

The function which assigns to each event of the space of outcomes a real number is called Random Variable. More formally, given a measurable space ( Ω, A), a random variable is a function defined on Ω with codomain in R, Borel-measurable with respect to the algebra A.
