Probability theory is a mathematics that studies randomness or uncertainty, and it is used to simulate the situation that experiments will produce different results in the same environment.

Statistics is not only statistics, but also includes investigation, collection, analysis and prediction. , its application range is very wide.

The difference between the two:

Probability theory is to analyze the possibility of events. This is usually based on a series of known conditions.

Statistics is the study and analysis of events that have happened. After analyzing the data, we can predict the most likely events in the future and provide the basis for decision-making. The knowledge of probability theory may be involved in the process of data analysis and prediction.
