Probability theory and mathematical statistics as an important part of mathematics in life has bee 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, bined 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 .Key words: Probability Mathematical Statistics Economic Life Random Variables Bayesian Law第 14 頁 共 15 頁 中國地質(zhì)大學(xué)2014屆本科生畢業(yè)論文 目錄摘要 ……………………………………………………………………………
