This paper presents a new noise-resistant fuzzy clustering approach based on probabilistic typicalities and cluster repulsion, denoted as RTCM, proposes a new iteration algorithm,furthermore, validates its converge.

The safety-monitoring index of seepage was determined by use of the typical low probability method,and the impermeability of the dam body and its foundation was analyzed through comparison of measured data with the index value.

Based on analysis of Gutian River First Stage Dam s prototype observed displacement data,this paper applied typical low probability method and confidence interval method to study the safty-monitoring index of crest horizontal displacement of No.

,it is proposed that the maximum takes monitoring indices of the structural analysis method and the minimum takes the result obtained by the typical low probability method.

This paper introduces the problems of some identical equation solved by the numerical characters of the classic probability and stochastic variable.

Abstract: Two methods of solving a classic probability problem were given.

Teaching of classical probability and the training of ability;

It′s applications in solving a class of classical probability problems related to numbers are illustrated.

This paper presents a fast method based on classical probability and the Laiyite to discriminate GPS abnormal data,which is simulated in VC++ and Matlab.

The two terms, traditional probability and quantum probability are defined.
