Problems solved by technology
In the process of learning probability and statistics, teachers generally prepare experimental props to explain the probability of events. Generally, it is more common to throw a coin to explain to students by determining the probability of the coin showing heads and tails. However, in the process, It is necessary to continuously record the number of projections and results artificially, but due to the excessive number of coin tosses, there may be recording errors. Therefore, it is particularly important to set up a mathematical simulation demonstration device for probability and statistics.

The invention provides a simulation demonstration device applied to mathematics of probability and statistics. The device comprises a transmission component used for transmitting a magnetic coin fed in advance to a coin slot formed in a coil feeding component arranged at the upper part of a block body cavity; the coin feeding component used for projecting the magnetic coin fed in advance at the coin slot, and projecting the magnetic coin into the block body cavity; an acquisition module arranged in the block body cavity, and used for acquiring a projection result of the coin feeding component;a control module arranged in the block body cavity, and used for recording the projection result and the corresponding number of projection times and displaying the result and the number on a displaymodule, meanwhile, controlling an open-close component arranged at the inner bottom of the block body cavity to open, to transmit the magnetic coin fed in advance to the transmission component, and controlling the open-close component arranged at the inner bottom of the block body cavity to close; and a drive motor arranged on one side of the transmission component, and used for driving the transmission component to execute corresponding subsequent operations. The magnetic coin fed in advance is controlled to be automatically projected, and the projection result and the corresponding number of projection times are recorded, so that recording accuracy can be improved.
Description
technical field [0001] The invention relates to the technical field of mathematics teaching, in particular to a mathematical simulation demonstration device for probability and statistics. Background technique [0002] Probability and statistics is a mathematical method for studying the statistical laws of random phenomena in nature. The main research objects of probability and statistics are random events, random variables and random processes. In the process of learning probability and statistics, teachers generally prepare experimental props to explain the probability of events. Generally, it is more common to throw a coin to explain to students by determining the probability of the coin showing heads and tails. However, in the process, It is necessary to continuously record the number of projections and results artificially, but due to too many coin tosses, there may be recording errors. Therefore, it is particularly important to set up a mathematical simulation demonst...
