日常生活中,人们经常要在不确定的情况下做出决定。如:彩迷在购买彩票前要预测某个数字是否会出现;远行者上飞机前决定是否买保险;病人家属根据医生所说的治愈机会决定是否进行手术,这些都是概率问题。概率是研究随机现象规律的科学。它为人们认识客观世界提供了重要的思维模式和解决问题的方法。而各种经济决策的做出也要求人们主动的去收集数据,整理数据和分析数据。概率与统计的基础知识已经成为未来一个公民的必备常识。下面结合自己的教育教学实践,谈谈新课程改革下的概率统计内容的特点及概率统计中常用解题方法。
In everyday life, people often make decisions under uncertain circumstances. Such as: the fans before buying a lottery to predict a certain number will appear; the traveler on the plane before deciding whether to buy insurance; patient’s family according to the doctor said the cure opportunity to decide whether to carry out surgery, these are the probability of the problem. Probability is the science of studying the law of random phenomena. It provides people with an understanding of the objective world of important modes of thinking and ways to solve problems. The various economic decisions made also require people to take the initiative to collect data, organize data and analyze data. The basic knowledge of probability and statistics has become a must for a citizen in the future. The following combination of their own education and teaching practice, talk about the characteristics of the probability of statistical content under the new curriculum reform and commonly used method of solving problems in probability statistics.
