This paper is fitting the continuous curves which are probability density functions to the binomial probability functions, negative binomial geometrics, poisson and hypergeometric. The main key in these fittings is the use of the derivative concept and common differential equations. https://cmde.tabrizu.ac.ir/article_3800_f745eda5291740921262040f296adf0c.pdf
