| Abstract: | This paper mainly gives a method that we can solve the first and second moment of binomial distribution, geometric distribution and Poisson distribution in statistics by derivative in mathematic analysis. And by this means, we can solve the higher order of Gamma distribution, exponential distribution and normal distribution by the higher derivative. |

| Keywords: | derivative binomial distribution Gamma distribution normal distribution moment |
