Problems solved by technology

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

Abstract

The invention discloses a probability demonstration device for calculating mathematics, comprising: a base plate; an RFID reader uniformly arranged on the base plate; the bottom surface of a glass plate is in contact with the identification end of the RFID reader; a lifter is arranged on the edge of the base plate; The projecting mechanism is arranged on the edge of the bottom plate and is opposite to the lifter, and its top is connected to the other end edge of the glass plate through the second hinge shaft. When the glass plate is parallel to the bottom plate, the top of the glass plate and the projecting mechanism are at the same level; An RFID electronic tag is pasted on the front and back of the coin respectively, and the two RFID electronic tags store different information respectively, and the RFID electronic tag matches the RFID reader. The present invention continuously tosses a coin, and recognizes the front and back of the coin after the toss, so that a large amount of experimental data can be obtained without manual repeated experiments, thereby confirming the experimental theory .

Description

technical field [0001] The invention relates to the field of demonstration equipment, in particular to a probability demonstration device for computing mathematics. Background technique [0002] The coin tossing test is a kind of demonstration probability experiment. This experiment is to toss a coin repeatedly, by counting the number of times the coin appears up and the number of times the coin appears up, and by comparing the number of times the number of heads and the number of times the coin appears up. The number of times tails come up leads to the theory that heads and tails are equally likely to come up 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. Under time constraints, only Carrying out a small amount of experiments to obtain a small amount of data will make the support for the theory wea...
