| Abstract: | Mr.Wang Zhikun,an academician of Chinese Academy of Sciences,pointed out a problem of maths in the .That is to choose one number randomly from the ten numbers of one to ten,supposing every number could be picked out by a probability of 1/10.Then mix the ten numbers and pick out one number again.Do it seven times,and seek the probability of A 5 which is equal to twenty.This article devlops the above problem into a theorem which can be applied to similar problems.Moreover,detail explantions are given to some designation problems in this article. |
