I participated in mathematical modeling last year, and I know a little! This requires probability, and it is better to express it in percentage system. If you want more statistical data, first draw the image of each group of data, first calculate it with the average value, then build a model and divide it into certain proportions according to the specific gravity, such as 0. 1, 0.2, 0.3, 0. 1, 0.3. This is an example. If you have time, you can spend more time building more models. Do you think it is reasonable to compare the established model with the real world? If we find out the reason, it should be a probability error. This modeling is not too difficult, it will be done in a few days!
