Description

Technical Field

[0001] The invention relates to the technical field of mathematics learning, in particular to a novel mathematics probability learning experimental device. Background Art

[0002] Probability is a science and technology that studies random events, and also studies numbers between 0 and 1. 0 means no event occurs, 1 means an event occurs, and a number greater than 0 and less than 1 is the probability. In mathematics learning, there are two major theorems that need to be learned, one is the addition theorem, and the other is the multiplication theorem. Among them, if doing something requires several steps, and each step has several possibilities, then the probability of the final result is equal to the product of the probabilities of each step, and this law is called the multiplication principle in probability.

[0003] However, the existing mathematics learning at least has the problem of being unable to conduct experimental learning of the multiplication principle of probability. For example, Chinese patent CN207149135U discloses a new type of mathematics learning. Although it can conduct experimental learning of probability by setting up a color ball probability collection box and a number ball probability collection box; but every time the device is used to conduct a probability experiment, it is necessary to manually put the ball into the ball probability collection box, which is inconvenient and easy to affect the experimental results. Therefore, a new type of mathematical probability learning experimental device is proposed here. Summary of the invention

The probability balls in the collecting mechanism can be quickly placed into the mixing ball mechanism for another probability experiment.
