在高中数学的学习中,排列组合是一个学习的重点,当然它也是学习的难点.排列组合问题多用于概率计算中.很多排列组合表面上看起来简单易解,但是实际上排列组合问题联系实际应用广泛并且灵活易变,且其涉及到的题型多种多样,让学生难以确定其解题规律.排列组合问题在近些年高考中的命题率越来越高,且其占据的比重及分值越来越高,为了使学生能够更好地学会如何做巧妙简单的解题,提高他们解题的能力.本文主要探究排列组合问题解答技巧.
In the study of high school mathematics, permutation and combination is a learning focus, of course, it is also difficult to learn. Permutation and combination problems are mostly used in probability calculation. Many permutations and combinations seem seemingly simple and easy to solve, but in fact arrange the combination problem with the actual Widely used and flexible and variable, and involves a variety of questions, so that students can not determine the problem-solving rules.Arranging combinatorial problems in recent years, the college entrance examination rate is higher and higher, and its share of the weight and In order to enable students to better learn how to do clever and simple problem solving and improve their ability to solve problems, this paper mainly explores the techniques of arranging and combing problem sets.
