摘 要：
Through the elaboration of 3 definitions of probability,several groups of concepts in probability statistics including random variables,discrete random variable and continuous random variable,non-correlativity and independency of random variable and independence of events,law of large numbers and central limit theorem are analyzed in the paper,and examples are also given to illustrate,which provide reference for improving students' understanding of concept learning,cultivating students to continuously mine concepts and developing learning quality of valuing thinking and diligent in thinking.
