Probability Curve Normal Distribution - Customization of Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:
This exhibition item is equipped with a probability demonstration device, which is installed inside a cylindrical transparent body. The probability device is shaped like a funnel, with a small ball passing through the middle of the upper and lower slots. Multiple nail posts are set in the lower part of the funnel. The audience clicks the "Start" button on the table, and can see that the lifting device on the side lifts all the balls one by one into the disc at the top of the exhibits. Then, the balls will fall from the circular holes at the same position on the disc surface and fall to the probability device. After all the balls have fallen, they can observe the camel hump shaped curve randomly formed below, thus understanding the normal distribution of probability.
