1. The addition principle is set to complete one thing there is a class method (either of these methods can be achieved
The purpose of accomplishing this), if the 1th kind of method, the 2nd class method has the kind, the first kind of method has the kind, then completes this matter to have a total of
In the recent learning Pattern recognition and machine learning often use the knowledge of probability theory, simply re-review the knowledge of probability theory. The most important point of learning probability theory is not the memory of the formula, but the understanding of the meaning behind the formula. (This is true of learning any knowledge, but the

Analysis of typical examples
Example 1. Set X1,X2, ... Xn is a sample from the overall x, in the following three cases, the E (), D (), E (S2) are respectively obtained.
(1) x~b (1,p), (2) x~exp (λ), (3) x~u (0,θ);
Analysis: It can be solved by using the expectation of common distributions, variance, and the property of S2 definition and expectation variance.
Solution: (1) due to x~b (1,p), E (x) =p, D (x) =p (1-p).
So E () =ex=p,
