Flexible Galton Board
Each time a red ball hits a green nail, it can bounce left or right with a certain probability. This Demonstration shows how balls accumulate in the bins at the bottom, approximating a binomial distribution.
The Galton board, also known as a quincunx or bean machine, is a device for statistical experiments named after English scientist Sir Francis Galton.
