Probability demonstration device for computational mathematics

Abstract

The invention discloses a probability demonstration device for computational mathematics. The probability demonstration device comprises a bottom plate; RFID readers which are uniformly arranged on the bottom plate; a glass plate, wherein the bottom surface of the glass plate is in contact with the identification ends of the RFID readers; a lifter which is arranged on the edge of the bottom plate;a throwing mechanism which is arranged on the edge of the bottom plate and opposite to the lifter, the top end of the throwing mechanism is connected with the edge of the other end of the glass platethrough a second hinge shaft, and when the glass plate is parallel to the bottom plate, the glass plate and the top of the throwing mechanism are located on the same horizontal plane; the front sideand the back side of the coin are respectively pasted with an RFID electronic tag, the two RFID electronic tags respectively store different information, and the RFID electronic tags are matched withthe RFID readers. According to the invention, one coin is continuously thrown, and the front and back sides of the coin are identified after the coin is thrown, so that a large amount of experimentaldata can be obtained on the basis of no need of repeated manual experiments, and the experimental theory is verified.

Description

technical field [0001] The present invention relates to the field of demonstration equipment, in particular to a probability demonstration device for computational mathematics. Background technique [0002] The coin toss test is a kind of demonstration probability experiment. This experiment is to toss a coin repeatedly, by counting the number of heads and tails of the coin, and by comparing the number of heads and the number of heads. The number of tails comes up to give the theory that heads and tails are the same probability when a coin is tossed. At present, when conducting this experiment, a large amount of data is often needed to obtain this theory, but when teaching demonstrations, there is often not a lot of time to demonstrate to students. A small number of experiments are carried out to obtain a small amount of data, so that the support for the theory will appear relatively weak. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overc...

At present, when conducting this experiment, a large amount of data is often needed to obtain this theory, but when teaching demonstrations, there is often not a lot of time to demonstrate to students. Under time constraints, only Carry out a small amount of experiments to get a small amount of data, so the support for the theory will appear relatively weak
