Galton board

Donate a coin for our exhibition. The path it takes through the board is random, but not all paths are equally likely. Repeating the experiment many times reveals that more coins go to the middle than to the boundary. More precisely, the coins follow the law of binomial distribution.

The board is named after the English scientist and scholar Sir Francis Galton (1822–1911).
