A probability demonstration device for mathematics teaching

Abstract

The invention relates to the field of mathematics, and especially relates to probability demonstration equipment for mathematics teaching. A to-be-solved technical problem is to provide the probability demonstration equipment which enables number balls not to fall easily during shaking, enables the number balls to be mixed uniformly enough and enables the convincing power of the fallen number balls to be stronger. In order to solve the above technical problem, the equipment provided by the invention comprises a box body, supporting legs, a laying-off hopper, a discharging tube, T-shaped baffleplates, and springs. The bottom of the box body is vertically provided with the supporting legs, and the upper part of the left side surface of the box body is provided with the laying-off hopper. The laying-off hopper is communicated with the box body, and the bottom of the box body is provided with the discharging tube. The discharging tube is communicated with the box body, and the left and right sides of the central part of the box body are respectively provided with a first through hole. The interior of each first through hole is provided with one horizontal T-shaped baffle plate in a manner of lateral symmetry. According to the invention, a first dialing device is driven by a drive unit to dial the number balls, and the equipment is provided with a second dialing device, thereby achieving the further dialing of the number balls.

Description

technical field [0001] The invention relates to the field of mathematics, in particular to a probability demonstration device for mathematics teaching. Background technique [0002] Mathematics is a discipline that studies concepts such as quantity, structure, change, space, and information. From a certain perspective, it is a kind of formal science. Mathematicians and philosophers have a range of views on the exact scope and definition of mathematics. [0003] Probability, also known as probability, chance rate, chance (probability) or possibility, is a basic concept of probability theory. Probability is a measure of the possibility of a random event occurring, and generally a real number between 0 and 1 represents the possibility of an event occurring. The closer to 1, the event is more likely to occur; the closer to 0, the event is less likely to occur, which is an objective argument rather than a subjective verification. [0004] When teachers teach probability to stu...
