Description

technical field [0001] The invention relates to a stirring device, in particular to a stirring ball device for probability teaching. Background technique [0002] When teaching probability knowledge to students, the teacher needs to use multi-color balls for stirring, and then randomly draws balls, and finally calculates the probability of drawing the same color balls. Currently, when stirring and drawing the balls, it is all manual Manually stirring the balls, manual stirring is not only time-consuming and laborious, but also uneven, so that the extracted probability is inaccurate. Therefore, there is an urgent need for an easy-to-use and easy-to-operate mixing ball equipment for probability teaching. Contents of the invention [0003] (1) Technical problems to be solved [0004] In order to overcome the disadvantages of stirring and extracting the small balls, the present invention manually stirs the small balls manually. Manual stirring is not only time-consuming and l...
