Physics, genetics, information theory and other disciplines can cultivate students' ability to think, analyze and solve problems with mathematical knowledge, and also help students to establish mathematical modeling ability, thus cultivating more applied mathematical talents for the society. ?

In daily life, there are also many cases that contain the knowledge of probability theory. For example, probability theory has very important applications in gambling, lottery and insurance.

Probability theory and mathematical statistics are very important basic courses in college mathematics, and they are also the only subjects that study the laws of random phenomena, guiding people to see the essence from the appearance of things. Moreover, probability theory and mathematical statistics have applications in natural science, daily life, engineering technology, economy, management, military and industrial and agricultural production.

Probability theory is a subject closely related to real life, but most people still have a common understanding of this subject: when tossing a coin, the probability of 0.5 is heads up and the probability of 0.5 is tails up. This is probability theory. Most people who have studied probability theory think that this course is theoretical, especially the law of large numbers and limit theorem, which are very divorced from reality and highly professional.
