How to explain the luck of playing cards in a scientific way?

Playing cards does have something to do with luck, but playing cards can be explained scientifically, because what kind of cards are caught in playing cards is a question of probability. 54 cards are almost fixed. Calculate the probability of which card you catch. If there are four people, it is 17 cards, which is the permutation and combination of the total number of 54 cards.

The most basic playing cards can be analyzed by formulas in probability theory in mathematics, such as total probability formula and Bayesian formula, which are the two most basic formulas in probability theory. These two formulas can make it systematic and complicated to determine all the permutations and combinations of 54 cards, and the probability of which combination we catch is fixed, because such a process can be calculated by computer, and we can work out three processes to get these four by writing. However, the calculation of 54 permutations and combinations is really too large to be done by hand, but we can use computers to help us calculate and finally determine the results through such a basic principle.

There are many things in this world that science can't explain. These things do exist, but playing cards is definitely not one of them. I always lose at cards, just because my skills and strategies are not good, I can't play psychological warfare, and I can't properly use my advantages to cover up my disadvantages. Then you are sure to lose. Although the combination is certain, it will change after you play some cards, and the fun of playing cards is in this endless change. The Jedi will survive.

When playing cards, some luck is that you happen to meet the right combination and may have restrained another combination. Your card is a little bigger than his, so your card is the best, but it happens that if your card is 9, it is not small, and your opponent is 10, then your card is very small. This is a relationship between restraint and being restrained, and it has nothing to do with luck.
