Mathematical probability learning device

Abstract

The invention discloses a mathematical probability learning device which comprises a random poking device, the random poking device is connected with a fastening shaft, the fastening shaft is provided with a magnetic correction rod and a through-hole roller, the two ends of the magnetic correction rod are provided with a positive magnetic pole and a negative magnetic pole, the outer side of the magnetic correction rod is provided with a magnetic correction disc, and an inner bag is arranged in the through hole roller. The inner bag is a hollow thin-walled cylinder, a bottom plate is arranged at the lower end of the inner bag, the bottom plate is a table top with the middle protruding, an inner hole is formed in the bottom plate, the through-hole roller is a hollow thin-walled cylinder, an annular bottom edge is arranged at the bottom of the through-hole roller, and a plurality of outer holes are formed in the annular bottom edge. Through the arrangement of the random stirring device and the magnetic force correction device, any accidental hole is connected with the inner hole to release small balls with random numbers, the influence of the external environment, the force applied by an experimenter, the angle and other stirring habits is almost avoided, the independence and randomness of events are achieved, and the experiment result is guaranteed. The device is compact in structure, convenient to carry, simple to operate and convenient to demonstrate.

Description

technical field [0001] The invention belongs to the field of mathematical probability demonstration tools, and in particular relates to a mathematical probability learning device. Background technique [0002] Probability, also known as probability, chance rate and probability rate, is a basic concept of mathematical probability theory, a real number between 0 and 1, and a measure of the possibility of random events. Probability can describe the internal mechanisms and regularities in complex systems, and is used in mathematics, statistics, physics, artificial intelligence, computer science, and philosophy. In the teaching of mathematics, probability demonstration devices are often used to strengthen students' understanding of probability. However, the existing probability demonstration devices have a single structure and can only perform probability demonstrations in a single way. Affected by the operation method, the individual has a large influence on the randomness of t...

In the teaching of mathematics, probability demonstration devices are often used to strengthen students' understanding of probability. However, the existing probability demonstration devices have a single structure and can only perform probability demonstrations in a single way. Affected by the operation method, the individual has a large influence on the randomness of the experiment, which is not conducive to improving the learning efficiency of students and the teaching efficiency of teachers
