Embodiment 1

[0027] This embodiment provides a mathematical probability demonstration model, and implements the present invention through basic necessary technical features to solve the problems raised in the technical background section of this application document.

[0028] Specifically, such as figure 1 As shown, the embodiment of the present invention provides a mathematical probability demonstration model, including a base 8, a pillar 9 is fixed on the base 8, a hollow shell 1 is fixed on the top of the pillar 9, and a plurality of surfaces are arranged in the hollow shell 1. The sphere 13 marked with numbers, the hollow shell 1 is provided with a rotating fan 5 for making the sphere 15 move irregularly, and the left and right sides of the lower end of the hollow shell 1 are respectively connected with the ball inlet pipe 4 and the ball outlet pipe 10. The free end of the ball-in tube 4 and the free end of the ball-out tube 10 are connected through the display tube 6, and the inner an...

Embodiment 2

[0032] This example is based on Example 1 and optimizes the implementation in Example 1, so that this example is more stable and has better performance during operation, but it is not limited to the one described in this example implementation.

[0033] Specifically, such as Figure 2-3 As shown, the pushing mechanism includes chutes 14 respectively provided at the bottom of the digital display tube 6 and the ball outlet tube 10 along the length direction, and the chute 14 of the digital display tube 6 is connected with the chute 14 of the ball outlet tube 10 And the surface of the joint is smooth and continuous. The slide groove 14 is slidingly fitted with a slide block 16, and a lifter 15 is arranged on the slide block 16. When the lifter 15 is in the lowest state, the upper surface of the lifter 15 does not exceed the The notch of the chute 14, when the lifter 15 is in the highest state, the upper surface of the lifter 15 does not contact the display tube 6 of the chute 14...

Embodiment 3

[0039] This example is based on Example 1 and optimizes the implementation in Example 1, so that this example is more stable and has better performance during operation, but it is not limited to the one described in this example implementation.

[0040] Specifically, the sphere 13 is provided with an RFID electronic tag 21 with a working frequency band of 13.56M. The RFID electronic tag 21 is used to store a number consistent with the number marked on the surface of the sphere 13. The identifier is used to identify The RFID reader 20 of the RFID electronic tag 21.

[0041] When identifying the numbers on the surface of the sphere 13, use the RFID electronic tag 21 with a working frequency band of 13.56M to be installed inside the sphere 13, and use the corresponding RFID reader 20 to identify the numbers. The numbers on the surface of the sphere 13 are more accurate, and at the same time, the recognition speed will be faster. Since the identification range of the 13.56M RFID...

Abstract

The invention discloses a mathematical probability demonstration model, which comprises a base, a pillar is fixed on the base, a hollow shell is fixed on the pillar, a sphere is installed in the hollow shell, a rotating fan is arranged in the hollow shell, and the hollow shell is respectively connected with a ball The tube and the ball outlet tube, the ball inlet tube and the ball outlet tube are connected by the display tube, the hollow shell is respectively opened with a through hole at the connection between the ball inlet tube and the ball outlet tube, and the height of the connection between the display tube and the ball outlet tube is low At the height of the connection between the ball tube and the display tube, the display tube is provided with a plurality of identifiers, and the base is provided with an input device for providing users with entering numbers, a first display screen for displaying the number of occurrences of the input numbers and A second display for showing how often the entered number occurs. The present invention randomly selects a certain amount of numbers and compares them with the numbers set by the corresponding players, repeatedly executes this step, obtains the results through statistics, and calculates the current lottery winning frequency in real time according to the statistical results.

Description

technical field [0001] The invention relates to the technical field of demonstration models, in particular to a mathematical probability demonstration model. Background technique [0002] Probability, also known as probability, chance, chance 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 more likely the event will occur; the closer to 0, the less likely the event will occur. It is often said that what is the percent certainty that someone will pass the test, or how likely is it that something will happen, are instances of probability. [0003] In real life, the lottery is a game that changes the game. The game of the lottery is to let the player choose a certain number of numbers first, and then randomly draw the number of the number. When the selected numbers are the same, i...
