Demonstrating Shannon entropy with 2 coins and 3 coins.

Summary

[edit]
Description
English: A bird with 3 coins can send 8 messages, while the rat with one coin less can only send half as many. Using coins to count messages is equivalent to counting in base 2 (starting at zero in this figure.) Instead of using 2 coins, the rat has the option of flipping a single 4-sided die. This informal peek at entropy can be modified to account for surprisal by adding the assumption the not all coins are "fair".
