The probability statistics is the mathematical method researching the statistical law of the random phenomena in the natural world. With the development of the science and technology, the probability statistics knowledge has been receiving more and more attention from people, which is broadly applied to the industrial and agricultural production, the national economy as well as our daily life. This paper, mainly around the relevant knowledge of Bernoulli scheme, normal school and mathematical expectation, discusses the application of the probability statistics to solving the practical problems.
