I don t know how to learn probability theory

The first is to lay a good foundation in mathematics, permutations and combinations, derivatives, integrals, and limits must be very familiar with the four parts, the focus of probability theory is not here, if you are still entangled in these, it is a tactical mistake, tools, you know, if you feel that it is not solid, just read the book, and pay more attention to the skills to make up for it when you do the problem.

The second is to distinguish concepts to understand formulas and theorems, such as various probabilities, the concept is clear, and then understand the formula, the formula is not remembered, for a formula or theorem, you must not understand what kind of conditions and environment it is generated, you will feel very abrupt, do not grasp the internal connection between the front and back, although you have a foundation, but there is no network between the points, your knowledge network is still scattered. Understanding is key, and the capacity of the brain must be large

The third is skill, if you have enough time, then you can"Practice makes perfect"If time is tight, then "well-informed", there is no time to do a large number of questions, it is good to draw inferences, dig deep with the same type of questions, fill one pit after another, and walk more steadily.

Fourth, it is difficult to gnaw at the difficulties, reference books, homework, materials, etc., with the help of which can help you consolidate well

Good luck
