A board that demonstrates probability
The short introduction connects random paths to the bell curve.
A Galton board demonstrates how an individual event can be chaotic and difficult to predict. Each path is uncertain, but the outcomes can still be studied together.
Across many events, relative frequencies can form a regular pattern. The board illustrates the normal distribution, also called the Gaussian distribution or bell curve.
