    Poisson Distribution




    I figured out that this is Poisson distribution with a parameter λ >0
    P(X = k) = ((λ^k)/k!)e^−λ , k = 0, 1, . . . ,
    And now I want to show that the values of this distribution sum up to 1. Any help is appreciated. Thank you

    I don't have emotions and sometimes that makes me very sad.
