Summary: | The utility model relates to the technical field of probability teaching, in particular to a probability demonstrator which comprises a rectangular frame, an ejection mechanism used for ejecting small balls into the rectangular frame is arranged on one outer side face of the rectangular frame, and dispersing mechanisms used for randomly ejecting the falling small balls are arranged on the front face of the interior of the rectangular frame at equal intervals. And one outer side surface of the rectangular frame is fixedly connected with two fixing seats which are symmetrical up and down. The utility model relates to an anti-theft device. Second springs are fixedly connected to the two sides of the two ends between the arc-shaped baffles and the cylindrical block, every two adjacent gears are meshed with each other, when a small sliding ball falls on one arc-shaped baffle, the second multi-lead-screw spring at the corresponding position can be compressed, then the small sliding ball is bounced off under the ela |
