This article introduces the definition and characteristic of mathematical expectation and variance through the examples of Binomial Distribution,Poisson Distribution,Uniform Distribution,Exponential Distribution and Normal Distribution,the mathematical expectations and variances of these distributions are also introduced.The relationship of definitions,characteristics and independence between covariance and correlation coefficient are discussed.Then the article introduces the definition,characteristic and use in daily life of Conditional Mathematical Expectation.At last with the type of matrix the article describes the mathematical expectation,variance and the degree of correlation between them,it also explains the characteristics of them.

Binomial distribution in this paper, S & P wow song distribution, uniform distribution, exponential distribution and normal distribution to introduce the mathematical expectation and variance of the definition, nature and the distribution of the mathematical expectation and variance, re-discussed and related covariance coefficient of the definition, nature and the independence of the relationship, and then discussed the conditions of the definition of mathematical expectation, the nature and application in life, and finally on the form of a matrix to describe the random vector of mathematical expectation, variance and between them the relevance and describes their nature.
