Advanced mathematics probability demonstration device

Abstract

The invention relates to the technical field of probability demonstration, and discloses an advanced mathematics probability demonstration device, which comprises a transparent box body, a plurality of coin slots are arranged on the top surface of the box body, the width of the coin slots is matched with the thickness of coins, the length of the coin slots is matched with the diameter of the coins, the coins are thin cylinders, two sides of each coin are smooth surfaces and are printed with identification codes, an identification device used for identifying the identification codes is arranged in the box body, and the identification device is respectively connected with a power supply and a probability statistics computer. According to the advanced mathematics probability demonstration device, the opportunity that the two sides face upwards after the coins fall is a completely random event; and the efficiency and accuracy of probability statistics are improved.

Description

technical field [0001] The invention relates to the technical field of probability demonstration, in particular to an advanced mathematical probability demonstration device. Background technique [0002] Probability and statistics are the focus and difficulty of advanced mathematics teaching. However, probability is relatively abstract and difficult to understand. In order to facilitate students to understand probability, probability demonstration is needed. [0003] The existing probability demonstration is to toss a coin or dice, check the number of times each side appears after falling, and then perform probability statistics. Because the patterns on the two sides of the coin are different, the weights of the two sides are also different, making the center of gravity deviate from the center of the coin , will affect the probability of two sides appearing. In addition, whether the toss starts with heads up or tails up will also affect the probability of the face of the fal...

[0002] Probability and statistics are the focus and difficulty of advanced mathematics teaching. However, probability is relatively abstract and difficult to understand. In order to facilitate students to understand probability, a probability demonstration is required

[0003] The existing probability demonstration is to toss a coin or dice, check the number of times each side appears after falling, and then perform probability statistics. Because the patterns on the two sides of the coin are different, the weights of the two sides are also different, making the center of gravity deviate from the center of the coin , will affect the probability of two sides appearing. In addition, whether the toss starts with heads up or tails up will also affect the probability of the face of the falling coin appearing. Therefore, the existing coin tossing method is not completely Random events. In addition, only one coin can be tossed each time. The probability and statistics work is cumbersome and time-consuming.
