Leave it to the French to give such an elegant word for a statistical concept - the Poisson distribution. This concept is trying to find out the probability of the success of a given number of events that happens over some area of time or space. Or to more simply state it let's put an example forward...like what is the probability of how many car accidents can happen over a certain road or what's the probability that we see a storm occur over a certain area. There's three examples that will be covered and conveniently enough that is an function in Excel (POISSON.DIST) that execute the Poisson formula.
