| Abstract: | This paper introduced the appliance of probability and statistics in reality, including classical model, formula of total probability, normal distribute, mathematics expectation and the central limit theorem. While it also discusses the widely uses of probability and statistics and the close relationship with the real life. Therefore, it lays the theoretical foundation for the practical uses with probability and statistics, and the basis of mathematics model. |
