# Fair Dice

A fair dice is a dice in which each face has an equal probability. In other words, there is an equal chance of landing on any of the dice faces. The main quality of a fair dice is that it is symmetric. So all 5 platonic solids are fair dice. There are also many more fair dice. Common fair dice made by dice makers and used in some games are: d2, d4, d6, d8, d10, d12, d20, d48, d120Check below to see how these dice are rolled and used by the players

## D2 (Dice with 2 sides)

Wondering what a dice with 2 sides looks like? Imagine a coin. It's a simple dice with only 2 sides. The fairness of this dice is same as the fairness of the coin. Recently, the fairness of the coin has been doubted. You can read about it here https://econ.ucsb.edu/~doug/240a/Coin%20Flip.htm.

This means that the fairness of the old traditional coin toss is questionable. However, if the toss is done by a computer then the physical reasons for unfairness are removed and it becomes a fair toss.
