纵观近年高考,排列组合、二项式定理几乎每年必考,考题多以选择填空题型出现,题小而灵,涉及的知识点也都在两三个左右。综合运用排列组合知识,加法,乘法原理;二项式定理及二项式系数的性质计算或论证一些较简单而“有趣”的小题已屡见不鲜。与其他知识点综合成题是潮流,不断变换这些知识点是发展的趋势。下面就一些可能出现的题型作评解,供大家复习参考。 Throughout the recent college entrance examination, the permutation and combination theorem and the binomial theorem are almost every year. Exam questions are often selected to fill in blank questions. The questions are small and spiritual, and the knowledge points involved are also about two or three. Comprehensive use of permutations and combinations of knowledge, addition, multiplication principle; Binomial theorem and the nature of the binomial coefficients to calculate or demonstrate some of the more simple and “interesting” topic has been common. Integration with other knowledge points is a trend, and changing these knowledge points is the trend of development. Below are some comments on the possible types of questions for review.
