How many days can the probability and mathematical statistics of self-taught postgraduate entrance examination be taken down?

Prepare high numbers, probability theory or linear algebra in turn. When to prepare depends on when the high number can be completed. After the advanced mathematics is finished, you can prepare the probability theory. Of course, the earlier the better, the later the time can be used to brush more questions.

Probability theory and mathematical statistics are a systematic mathematical discipline, which answers the numerical characteristics and practical experience of things in daily life and has very strong application. The content involved is also more complicated. If you study in school, it will take three to four months to remember the knowledge points.

event

Events include unit events, event space, random events, etc.

The only and independent result that may occur in a random experiment is called a unit event, which is represented by E, and the set of all possible unit events in a random experiment is called an event space, which is represented by S. For example, in a random dice test, if a unit event is represented by the number of points obtained, there may be six unit events in a * * *, and the event space can be represented by S={ 1, 2, 3, 4, 5.
