概 率 论 与 数 理 统 计 在 日 常 经 济 生 活 中 的 应 用 摘要：数学作为一门工具性学科在我们的日常生活以及科学研究中扮演着极其重要的角色。概率论与数理统计作为数学的一个重要组成部分，在生活中的应用也越来越广泛，近些年来，概率论与数理统计知识也越来越多的渗透到经济学，心理学，遗传学等学科中，另外在我们的日常生活之中，赌博，彩票，天气，体育赛事等都跟概率学有着十分密切的关系。本文着眼于概率论与数理统计在我们生活中的应用，通过前半部分对概率论与数理统计的一些基本知识的介绍，包括概率的基本性质，随机变量的数字特征及其分布，贝叶斯公式，中心极限定理等，结合后半部分的事例分析讨论了概率论与数理统计在我们生活中的指导作用，可以说，概率论与数理统计是如今数学中最活跃，应用最广泛的学科之一。 关键词：概率论 数理统计 经济生活 随机变量 贝叶斯公式 Probability Theory and Mathematical Statistics In our daily economic life Abstract: As an instrumental discipline, Mathematics plays a very important role in our daily life and scientific research. Probability theory and mathematical statistics as an important part of mathematics in life has become increasingly widespread in recent years, probability theory and mathematical statistics knowledge is increasingly penetrate into economics, psychology, genetics and other disciplines, in addition to our everyday lives, are related to the probability of gambling, lottery, weather, sports and other school has a very close relationship. This article focuses on the theory of probability and mathematical statistics application in our lives, through the introduction of the first half of some basic knowledge of probability theory and mathematical statistics, numerical characteristics, including the fundamental nature of probability, random variables and their distributions, Bayesian formula , the central limit theorem, combined with the second half of the cases discussed the theory of probability and mathematical statistics in guiding role in our lives, we can say, probability theory and mathematical statistics is now one of the most active, the most widely used discipline .
