概率知识与现实生活息息相关。而且概率问题与函数、不等式以及统计初步等其他数学知识交汇在一起,可以考察学生综合运用概率的有关知识分析问题解决问题的能力,能体现数学高考在知识网络的交汇点命题的特点。因此,概率问题越来越受到命题者的青睐。由于概率问题具有一定的难度,学生学习及运用中会产生许多困惑,为了让学生能正确的理解并掌握,提高求解概率问题的技巧,本人结合具体实例谈谈几点看法,仅供参考。一、注重知识的前后联系,处理好与排列组合的关系
Probability knowledge and real life are closely related. Moreover, the probabilistic problem integrates with other mathematical knowledge such as function, inequality and preliminary statistics, which can examine students’ abilities to solve problems through knowledge-based analysis of probabilities of using probabilities and embody the characteristics of mathematics entrance examinations in knowledge networks. Therefore, the probability problem is more and more favored by the proponents. Due to the difficulty of probabilistic problems, students will have a lot of puzzles in their study and application. In order to help students understand and master correctly and improve their skills in solving probabilistic problems, I will discuss some specific examples and provide them for reference purposes only. First, pay attention to knowledge before and after the relationship, deal with and arrange the combination of relations
