Draw lots principle

The principle of drawing lots comes from the total probability formula, which means that the order of drawing lots has nothing to do with the probability of winning lots.

For example, in the test batch of 10, 4 people were difficult to sign, 3 people participated in the lottery (not put back), A was the first, B was the second, and C was the last. When seeking A, it was difficult to sign, both A and B were difficult to sign, A was difficult to sign, B was difficult to sign, and A, B and C were all difficult to sign. In fact, even if these ten tickets are drawn by 10 people, because four of them are difficult to draw, the probability of each person winning the ticket is 4/ 10 regardless of the order in which he draws.

Just like 100000 people draw 100000 lottery tickets with only10 grand prize, in no particular order, everyone's winning probability is10000010, which is one in ten thousand. This is called the lottery principle in probability theory.

Draw lots:

Drawing lots is a folk custom in China, and it is also one of the forms of divination. At present, Taoist temples, temples and folk temples have mostly placed sign boxes for people to draw and ask for directions. Like gossip, drawing lots is a popular forecasting method for ancient people in China to judge good fortune and bad fortune. The basis for judging good or ill luck is the number of poems signed and the allusions of poems signed.

Every sign must be signed, and the signed poem is an allusion, and these poems and allusions were created by ancient literati. The content is rich and colorful, including many truths of theology, literature, history, religion and philosophy, which we have to explore and study.
