高中数学《排列组合的常见模型》基础知识与练习题(含答案)

高中数学《排列组合的常见模型》基础知识与练习题(含答案)

高中数学《排列组合的常见模型》基础知识与练习题(含答案)一、基础知识:(一)处理排列组合问题的常用思路:1、特殊优先:对于题目中有特殊要求的元素,在考虑步骤时优先安排,然后再去处理无要求的元素。

例如:用0,1,2,3,4组成无重复数字的五位数,共有多少种排法?解:五位数意味着首位不能是0,所以先处理首位,共有4种选择,而其余数位没有要求,只需将剩下的元素全排列即可,所以排法总数为44496N A =⨯=种2、寻找对立事件:如果一件事从正面入手,考虑的情况较多,则可以考虑该事的对立面,再用全部可能的总数减去对立面的个数即可。

例如:在10件产品中,有7件合格品,3件次品。

从这10件产品中任意抽出3件,至少有一件次品的情况有多少种解:如果从正面考虑,则“至少1件次品”包含1件,2件,3件次品的情况,需要进行分类讨论,但如果从对立面想,则只需用所有抽取情况减去全是正品的情况即可,列式较为简单。

3310785N C C =−=(种) 3、先取再排(先分组再排列):排列数mn A 是指从n 个元素中取出m 个元素,再将这m 个元素进行排列。

但有时会出现所需排列的元素并非前一步选出的元素,所以此时就要将过程拆分成两个阶段,可先将所需元素取出,然后再进行排列。

例如:从4名男生和3名女生中选3人,分别从事3项不同的工作,若这3人中只有一名女生,则选派方案有多少种。

解:本题由于需要先确定人数的选取,再能进行分配(排列),所以将方案分为两步,第一步:确定选哪些学生,共有2143C C 种可能,然后将选出的三个人进行排列:33A 。

所以共有213433108C C A =种方案(二)排列组合的常见模型1、捆绑法(整体法):当题目中有“相邻元素”时,则可将相邻元素视为一个整体,与其他元素进行排列,然后再考虑相邻元素之间的顺序即可。

例如:5个人排队,其中甲乙相邻,共有多少种不同的排法解:考虑第一步将甲乙视为一个整体,与其余3个元素排列,则共有44A 种位置,第二步考虑甲乙自身顺序,有22A 种位置,所以排法的总数为424248N A A =⋅=种2、插空法:当题目中有“不相邻元素”时,则可考虑用剩余元素“搭台”,不相邻元素进行“插空”,然后再进行各自的排序注:(1)要注意在插空的过程中是否可以插在两边(2)要从题目中判断是否需要各自排序例如:有6名同学排队,其中甲乙不相邻,则共有多少种不同的排法解:考虑剩下四名同学“搭台”,甲乙不相邻,则需要从5个空中选择2个插入进去,即有25C 种选择,然后四名同学排序,甲乙排序。
