Background
Probability is the basic concept of probability theory. Probability is a measure of the likelihood of occurrence of a random event, typically expressed in terms of a real number between 0 and 1. The estimated probability of the Karl-Darno preliminary system was as early as 16 th century. The probability is a value that measures the probability of occurrence of an contingency, which occurs several times (denoted by Y) if multiple repetition tests (denoted by X) are performed. Using X as denominator and Y as numerator, a value (represented by P) is formed, and P becomes the probability of A occurrence in a plurality of experiments where P is relatively stable at a certain value. In the most primitive probability studies, the probability of a certain occurrence needs to be verified through repeated experiments, and hundreds of experiments and even tens of thousands of experiments need to consume a great deal of manpower and time to perform experiments and records.
