Problems solved by technology

[0003] At present, there are two kinds of mathematical probability and statistical models: the statistical probability of coin heads and tails and the statistical probability model of normal distribution. However, there is no probability and statistical model for a large number of random variables. It is more intuitive to count a large number of random variables. There are Help develop students' interest in learning
[0004] After long-term study and observation, a mathematical stochastic probability statistical model has been developed, but there is no such model in the market

Embodiment Construction

[0027] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings.

[0028] Such as figure 1 , figure 2 As shown, a mathematical stochastic probability statistics model includes a cone 6, a number of partitions 7 are evenly distributed on the cone 6, and slideways 8 are set between the partitions 7; the variable sphere falls from the top of the cone 6, and passes through the The slideway 8 on the cone 6 is used for random data statistics. For the convenience of observation, the cone 6 is provided with a transparent shell 3, and the top of the transparent shell 3 is provided with a channel 2, which can avoid external factors. A funnel is provided above the channel 2 1. It is convenient to put variable spheres; in order to facilitate the placement and recovery of variable spheres, a detachable lower seat 4 is provided at the bottom of the transparent shell 3 and the c...

Abstract

The invention discloses a mathematical random probability statistical model, and belongs to the field of probability statistics. The mathematical random probability statistical model comprises a cone, wherein a plurality of division plates are uniformly distributed on the cone, and slide ways are arranged among the division plates; a variable sphere drops from the upper side of the cone, and random data statistics is carried out randomly through the slide ways on the cone; for the convenience of observation, a transparent shell is arranged outside the cone, and a passage is arranged at the top of the transparent shell, so that external factors can be omitted; a funnel is arranged above the passage to conveniently throw the variable sphere; and in order to conveniently place and recycle the variable sphere, a detachable lower seat is arranged at the bottom of each of the transparent shell and the cone. According to the mathematical random probability statistical model disclosed by the invention, the slide ways and the movement locus of the variable sphere are arranged by the cone, so that when a large number of random variables are counted, a more intuitive and efficient effect is realized.

Description

technical field [0001] The invention relates to the field of probability statistics, in particular to a mathematical random probability statistics model. Background technique [0002] Mathematical probability statistics is based on the statistical laws of a large number of similar random phenomena, making an objective scientific judgment on the possibility of a certain result of a random phenomenon, and making a quantitative description of the possibility of this occurrence; comparing these possibilities The size and the relationship between them are studied to form a whole set of mathematical theories and methods. [0003] At present, there are two kinds of mathematical probability and statistical models: the statistical probability of coin heads and tails and the statistical probability model of normal distribution. However, there is no probability and statistical model for a large number of random variables. It is more intuitive to count a large number of random variables...
