摘要
本文介绍了概率统计的某些知识在实际问题中的应用,主要围绕古典概型,全概率公式,正态分布,数学期望,极限定理等有关知识,探讨概率统计知识在实际生活中的广泛应用,进一步揭示概率统计与实际生活的密切联系,为应用概率知识解决实际问题,数学模型的建立,学科知识的迁移奠定一定的理论基础。
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.
