Dice has six sides. Theoretically, every time two dice are thrown together, 6*6=36 kinds, namely11[12] [13] [14] [15] [/kloc-5].
2 1 2 2 [2 3] [2 4] [2 5] [2 6]
3 1 3 2 3 3 [3 4] [3 5] [3 6]
4 1 4 2 4 3 4 4 [4 5] [4 6]
5 1 5 2 5 3 5 4 5 5 [5 6]
6 1 6 2 6 3 6 4 6 5 6 6 But the two dice are the same, so it can be seen from the above figures that there are actually only 2 1 different results.
Events that may or may not occur under the same conditions. For example, it is a random event to randomly select one from a batch of goods with genuine products and defective products, and "what is extracted is genuine products".
Suppose a random phenomenon is tested and observed n times, in which event A appears m times, that is, its frequency is m/n. After a lot of repeated experiments, m/n is often closer to a constant (see Bernoulli's law of large numbers for details).

If the probability of accidental events is determined through long-term observation or a large number of repeated experiments, it is statistical probability or empirical probability. The discipline that studies the internal laws governing accidental events is called probability theory. It belongs to a branch of mathematics. Probability theory reveals the manifestation of the inherent law contained in accidental phenomena.
Therefore, probability plays an important role in people's understanding of natural and social phenomena. For example, it is necessary to use probability theory to determine how much social products should be deducted before being distributed to personal consumption and how much accumulation should account for in national income.
Usually, an event in an experiment consists of basic events. If an experiment has n possible results, that is, the experiment consists of n basic events, and all the results are equally likely to appear, then such events are called allelic events.
