I think, classmate, you don't seem to understand the true meaning of probability Probability is a measure to describe the possibility of a certain result. Before there is no result, the probability of every possible result exists objectively, some are large and some are small, and it is also possible that the probability of any result is the same, that is, the probability is equal. The teacher said that the probability is equal, which means that the probability of each result is the same before there is no result, which is the embodiment of fairness.
Please refer to this humble opinion.
