无组别(不考虑分组序号)平均分组问题是排列组合问题中比较典型的一类问题.对这类问题,一种通用的解法是将分组平等看待,再由无组别特征去掉重复计数的部分,得到问题的解.这种解法多年被沿用下来,这里,介绍一种新解法,并介绍由此深入探究而得到的猜想.问题1将8人分成人数相等的两组,有几种分法?解法1(通用解法)8人中任取4人,有
No group (no group number is considered) The average grouping problem is a typical problem in permutation and combination problems. A general solution to this kind of problem is to treat the grouping equally and eliminate the grouping by repeated grouping Partially, get the solution of the problem .This solution has been used for many years, here, introduce a new solution, and introduce the conjecture obtained from this in-depth inquiry.Question 1 will be divided into 8 equal number of two groups, there are several points Method 1 (general solution) 8 people in any 4, there
