Rules of the Game
This machine was invented by Francis Galton around 1860. It consists of metal rods arranged in the shape of a triangle. They are represented by black dots on the screen. We will throw blue balls from above. They will bounce off the rods to the left or right with the same probability. When all of them fall, will there be more of them in the center, in the edges, or evenly? After doing the experiment, compare the result with the Gauss bell. You can change the probability that the ball goes to the right. The distribution of balls will change, the Gaussian bell will change too. Have you detected 3 changes?
