What exactly does probability mean? What exactly does a 50% winning percentage mean? I hope everyone can help me, and everyone who answers my questions wishes a happy and healthy life.

Probability, also known as probability, probability, probability or possibility, is the basic concept of probability theory. Probability is a measure of the probability of random events. Generally, the real number between 0 and 1 indicates the probability of events. The closer to 1, the more likely it is to happen. The closer to zero, the less likely it is to happen. People often say how sure someone is to pass the exam and how likely something is to happen. These are examples of probability.

Question 1 For example, a winning percentage is 10%, which means you can win once if you play 10 times. So what will it actually look like? Please answer this.

A: 10 times is likely to win once, or it is most likely to win once. Of course, the actual result may be that 1 time did not win, or1time won. It's just that you are more likely to win 1 time than twice, and the possibility of winning1time is the smallest, so you can't make such an expectation in advance.

Question 2: This is still about the first question. Please judge whether my understanding of winning percentage 10% is correct: that is to say, in reality, I may win once in the eighth game, or once in the 12 game, but overall, I win once in ten games. Example: lose 7 times first-win 8 times. Or 1 1 lose-12 win. That is to say, if you lose 9 times, you will win at-10 on average, and only fluctuate around this 10? Excuse me, do I understand correctly?

A: Your understanding is correct, but remember that it is possible, not certain. On average, it is more likely to win once in ten games.

Question 3: Since you won, you may win once in the eighth game or once in 12 game, but generally speaking, you win once in ten games. Is it possible to start counting after I win and then win the next game? Just won, 10% winning rate: Is it possible to win, lose, lose, lose, lose?

A: There may be such a situation as you said. Since it is possible, it is impossible to determine which game will win and how many games will win, because probability represents possibility and cannot be determined.

The last four questions: where should I study and give a place?

Answer: Probability theory belongs to the category of mathematics, and there are special teaching materials, which can be taught by yourself after purchase. You can also take part in correspondence study for math majors.
