The value of probability
Why study probability is to examine a large number of samples, mainly for evaluation. In fact, it is not important to take the specific value of a random variable at a certain time. What is important is the number of certain types of products that appear in a wide range of target products, such as evaluating two sets of production lines and evaluating N sets of processes, such as Guo Taiming's production line and a processing in Shenzhen Which factory is better? Probability is more meaningful in terms of a certain number of scenarios (where both space and time and temporal samples are relatively broad).
