Fair

If an object, especially a coin or die, is considered "fair", it is not skewed and has an equal probability of producing any of its outputs. For example, a fair coin has a $1/2$ chance of landing heads and a $1/2$ chance of landing tails. Similarly, a fair six-sided die has a $1/6$ chance of showing any positive integer from 1 to 6, inclusive, on its top face.
