Details

To calculate the Poisson distribution, the user should give two number ( the number of times the phenomenon and the number of occurrences). The result is a discrete probability distribution that expresses, from a mean frequency of occurrence, the probability that a certain number of events will occur during a certain period of time. The Poisson distribution formule is the following:

Examples

    #data creation
    lam = 2
    k = 3
