The Analysis and Discovery Base on a Fallible Probability Problem
Zhang Ron · College Mathematics · 2014
The pile problem is one of the difficulties in permutations and combinations.Through the analysis of a fallible probability problem,the pile problem is extended,the definition of same structure of the pile problem is given.The permutations and combinations with the same structure are studied,the calculation formula of the same structure is given,and an example using the property of discrete type radom variable is used for verification.In addition,a symbolic operation of identity is founded and proved.
