2 dice probability
For two dice, there were several possibilities:
1. ** Single number probability **:
- Each die had six sides, and the numbers were 1, 2, 3, 4, 5, and 6. When a die is rolled, the probability of each number appearing is 1/6. When two dice were thrown, for example, the probability of both dice rolling a 1 was 1/6. Therefore, the probability of both dice rolling a 1 (the combination of 1 and 1) was (1/6)×(1/6)=1/36. Similarly, any particular combination of numbers (such as 3 and 5) has a probability of 1/36.
2. ** Point sum probability **:
- The sum of the points was 2 (1 + 1), and there was only one possibility. The probability was (1/6)×(1/6)=1/36.
- The sum of the points is 3 (1+2 or 2 + 1). There are two possibilities, and the probability is 2/36.
- The sum of the points was 4 (1+3, 2+2, 3+1). There were 3 possibilities, and the probability was 3/36.
- The sum of the points is 5 (1+4, 2+3, 3+2, 4+1). There are 4 possibilities, and the probability is 4/36.
3. ** Dice size probability (1 - 6 is small, 7 - 12 is big)**:
- There were a total of 6x6 = 36 combinations of the two dice. Among them, there were 15 situations where the sum of points was 1 - 6 (small), and 21 situations where the sum of points was 7 - 12 (large). However, since it was impossible for two dice to have a point, the probability of a small point appearing was 5/11 (about 45.45%), and the probability of a big point appearing was 6/11 (about 54.55%).
4. ** The probability that the sum of the two dice numbers is odd (assuming the first die numbers are 1, 2, 3, 3, 5, 6, and the second die numbers are 1, 2, 4, 4, 5, 6)**:
- For the first die, the probability of an odd number appearing was 4/6 = 2/3, and the probability of an even number appearing was 1/3. For the second die, the probability of an odd number appearing was 2/6 = 1/3, and the probability of an even number appearing was 2/3. To get the odd sum, there are two situations: if the first die is odd and the second die is even, the probability is 2/3×2/3 = 4/9; if the first die is even and the second die is odd, the probability is 1/3×1/3 = 1/9. Therefore, the total probability was 4/9+1/9 = 5/9.

Chance Dice
The probability of the die facing up was a concept related to probability. For a single standard die, since it had six sides marked with the six numbers 1, 2, 3, 4, 5, and 6, under the assumption that the texture of the die was uniform (ideal state), the probability of each side facing up was equal, 1/6.
When considering the combination of multiple dice, the calculation became more complicated. For example, to calculate the probability of the total number of dice, one needed to find all the combinations that obtained the total number of dice and divide it by the total number of combinations, 36 (6×6). For example, a total of 12 could only be a case where both dice rolled 6 points, so the probability was 1/36. There were two cases where a total of 11 points (one dice rolled 6 points, the other rolled 5 points, or vice versa), and the probability was 2/36, which was 1/18.
In addition, from a practical point of view, some dice might not be completely uniform. For example, a hole-digging die had six small pits dug on each side of the six points, while only one small pit was dug on the one point side. This made the six points side lighter than the one point side. According to the law of free fall, the probability of one point facing down was higher than the probability of six points facing down. However, in formal gambling or professional use scenarios, special processing methods would be used to ensure that the probability of each side of the die was as uniform as possible. For example, the pits dug were directly filled with raw materials to retain the color shadow of the pit, the size of the pits on each side was controlled to balance the quality, or the use of a regular square with no pits was directly used and numbers or points were written on each side.

The God of Dice, Decius
In the Middle Ages, dice were a gambling tool. When gamblers prayed, Decius, the god of dice, would have a higher status than God. Dice first appeared in ancient Egypt, and then in India, the common six-point dice appeared. It was originally a tool for divination. Nowadays, there were many ways of gambling related to dice. Because of addiction to gambling, countless people lost their fortunes and even lost their lives.

The probability of dice rolling
Rolling dice was a classic example of probability.
For a single standard die, because it had six sides, each marked with the six numbers 1, 2, 3, 4, 5, and 6, the chances of each number appearing were equal. Therefore, when throwing a single die, the probability of any number appearing in the result was 1/6.
When there were multiple dice involved, the probability calculation would be more complicated. Take two dice as an example, if you consider the size of the dice,(1 - 6 is small, 7 - 12 is big), because there are a total of 6×6 = 36 combinations of the number of points on the two dice. Among them, there are 15 cases where the sum is 1 - 6 (small), and there are 21 cases where the sum is 7 - 12 (big). However, since it is impossible for the two dice to appear, the actual probability of small appearing is 5/11 (about 45.45%), and the probability of big appearing is 6/11 (about 54.55%).
If there were three dice, each die would have six situations, and there would be a total of 6x6x6 = 216 combinations. For example, if one calculated the probability of rolling a big die, there would be three kinds of big situations (namely, 4, 5, and 6 points) for each die. There were a total of 3×3×3 = 27 kinds. Therefore, the probability of a big situation appearing was 27 × 216 = 1/8. Similarly, the probability of a small situation appearing was also 1/8. The probability of a leopard appearing (three dice with the same number of points, such as 111, 222, etc.) was 6 × 216 = 1/36.
In addition, in theory, if the structure of the die was uneven, for example, the dots were hollowed out, and the six small round pits on the six dots were lighter than the one on the opposite side, then the probability of the six appearing would be greater than the one. However, in the ideal standard die situation, the probability of each number was 1/6. At the same time, there were many other situations in the probability calculation of dice rolling, such as the probability calculation of the sum of two dice numbers being odd, which could be solved by different probability methods (such as the step-by-step probability calculation method in junior high school or the combination knowledge method in high school).

dice-rolling probability
The condition probability refers to the probability of event A happening under the condition that event B has already happened. It is recorded as P(A| B)。The following is an example analysis of the probability of dice rolling.
Suppose we have two dice. Event A is that the sum of the two dice is 8, and Event B is that the first die rolls a 3.
First, calculate the probability of event A without any conditions. There were a total of 6×6 = 36 possibilities for the outcome of the two dice. There are five cases where the sum of points is 8:(2,6),(3,5),(4,4),(5,3), and (6,2), so P(A)=5/36.
Then, the probability of event B is calculated. The probability of the first die rolling a 3 is 1/6, which is P(B)=1/6.
The only situation where both events A and B occur at the same time is (3,5), so P(A Empyrean B)=1/36.
According to the formula P(A| B)=P(A Empyrean B)/P(B). Under the condition that the first die rolls a 3, the probability of the sum of the two dice points being 8 is P(A| B)=(1/36)/(1/6)=1/6。
For example, Event C was the difference between the two dice being 1, and Event D was the second die rolling a 4. Similarly, P(C) was first found. There were 10 cases where the difference between the points was 1:(1,2),(2,3),(3,4),(4,5),(5,6),(2,1),(3,2),(4,3),(5,4), and (6,5), so P(C)=10/36. The probability of event D is P(D)=1/6. There are two cases where events C and D occur at the same time: (3,4) and (5,4), so P(C Empyrean D)=2/36. Under the condition that the second die rolls a 4, the probability of the difference between the two dice being 1 is P(C| D)=(2/36)/(1/6)=1/3。
In short, when calculating the conditioned probability of rolling the dice, the key was to clarify the relationship between the events, separately calculate the probability of the event occurring alone and the probability of them occurring at the same time, and then use the conditioned probability formula to calculate.

Mathematical problems with dice
Here are some mathematical questions about dice:
1. ** Problem with probability calculation **
- When rolling a pair of dice, calculate the probability of getting a specific number. For example, the famous mathematician and philosopher Gottfried Leibniz believed that the probability of rolling 11 and 12 with a pair of dice was the same, but this idea was wrong. A total of 12 would only appear in one situation (both dice were 6), while a total of 11 would appear in two situations (5 and 6 or 6 and 5).
- If a pair of dice was thrown, the probability of the final number being an even number and the probability of the total number being even and odd were exactly the same. The total number of a pair of dice rolled was between 2 and 12, and the probability was calculated by analyzing the combination of different results.
2. ** Questions related to expectations **
- For example, in a game of eight dice rolls, a player needed to roll a 6 in the game of eight dice rolls. He had rolled three times but none of them was a 6. If a certain percentage of the money was taken out from the bet to the player and he was asked to give up the fourth chance to throw the dice (only this time), how much money was given to him to be fair? This involved determining a fair compensation amount based on the concept of expected value. For a gamble with a bet of V(x) and an outcome of x, the expected value was the probability of the average: expected value (V)=V(x1)p(x1)+V(x2)p(x2)+…If the player's expectation of the transaction remained the same, it could be considered a fair transaction.
3. ** The relationship between the result of the simulated dice and the probability **
- For example, he could simulate dice rolling to study the relationship between theoretical probability and actual results. For example, someone used excel to randomly generate the form of 1 - 4 to simulate dice throwing (A, B, C, D were replaced by 1, 2, 3, 4), and simulated the answers to the multiple-choice questions of the national college entrance examination science subjects to study the scores that could be obtained by throwing the dice, thus reflecting the relationship between the random choice answer (similar to the random result of the dice) and the correct answer, as well as the corresponding probability.

U-roll the dice
Dice was a small square made of ivory, bone, or plastic. Each side was engraved with numbers from one to six. A pair of dice could be used to play various games or gamble. The operation of rolling the dice was to shake the dice first, then throw them so that both dice would stop on a flat surface at will. In addition, there was also a casual Mini games called " Zilch Dice Gambling ". In some areas, dice was also used for bar games." God doesn't roll dice " was a famous statement used by Einstein to refute the physicist Bohr's explanation of quantum mechanics.
