Abstract

The present invention provides an advanced mathematics probability demonstration device. The device comprises: a barrel, wherein the bottom portion of the barrel is provided with a U-shaped groove having a downward opening; a transparent upper cover, wherein the transparent upper cover covers the barrel; a bottom cover, wherein the periphery of the top portion of the bottom cover is inserted intothe U-shaped groove, a transparent separator is arranged between the transparent upper cover and the barrel, the top portion of the transparent upper cover is provided with an image device, a drum head is arranged between the bottom cover and the barrel, and dices or coins are put on the drum head; two clamping legs configured to clamp edge of a table and a regulation leg which are arranged at theouter side of the periphery of the bottom surface of the bottom cover; and a vibration device comprising a guide pillar and a spring, wherein the guide pillar is slidingly inserted into the center ofthe bottom plate of the bottom cover. The advanced mathematics probability demonstration device employs an image device to project the dices or coins to a large screen in the probability demonstration experiment so as to allow all the students to perform statistics of the probability demonstration experiment.

Description

technical field [0001] The invention relates to a teaching device, in particular to a high mathematics probability demonstration device. Background technique [0002] Chinese patent CN206594899U discloses a teaching demonstration device for university mathematics probability events, which includes a transparent cylinder with an upper opening, and a rotating device for placing and throwing coins or dice in the cylinder from top to bottom, and a clapboard flip device, the bottom of the drum is provided with a shock absorber, the side wall of the drum near the bottom is provided with an opening, and a slidable cover is provided at the opening. Place the dice and coins on the surface of the circular plate of the rotating device. The rotating device uses centrifugal force to throw the dice and coins horizontally and freely fall to the horizontal partition set in the bucket for statistics. The partition turning device can rotate the partition to a certain value. Angle, dump the d...
