Demonstration device for advanced mathematics probability

Abstract

The invention discloses an advanced mathematics probability presentation device. The statistical right-side up probability is equal to the statistical reverse-side up probability when coins are manually thrown, and the time-consuming and labor-consuming problem is solved by the device. A plurality of drums are arranged inside side walls; first air cylinders are arranged in the drums; electromagnets are arranged on piston rods of the first air cylinders; springs sleeving the outside of the first air cylinders are arranged in the drums; the upper parts of the springs are fixed with metal convex pieces; an oblique pad is arranged on the upper part of the inner cavity of each drum; a coin throwing space is enclosed by the plurality of drums, and a coin supply assembly is arranged among the drums and the side walls; the coin throwing space is equipped with an end cover which is in a hollow structure, and the upper end of the end cover is opened; the upper part of a pedestal is equipped with a poke rod driven by a motor, and a coin outlet is arranged between the installing end of the end cover and the pedestal. According to the presentation device, the environment is identical when the coins are thrown every time, the precision of testing results and the testing persuasion are ensured, and the device is convenient and simple in operation.

Description

technical field [0001] The invention relates to the technical field of advanced mathematical probability, in particular to a demonstration device for demonstrating that the probabilities of flipping a coin are equal to heads and tails. Background technique [0002] In advanced mathematics, probability is a difficult knowledge point to understand. When tossing a coin, to count the probability that the coin is either heads up or tails up is equal, the statistician needs to hold the coin and throw it into the air, then wait for the coin to fall on the ground, and repeat the above action several times. In this way, it takes a lot of time for the statistician, and it is time-consuming and labor-intensive. Contents of the invention [0003] The purpose of the present invention is to provide a high-level mathematical probability demonstration device, which is used to solve the time-consuming and labor-intensive problem when manually tossing a coin to count the probabilities of h...
