Extension:
A 'fair' dice, 'fair' spinner, and 'fair' coin are all objects used in probability where each possible outcome has an equal chance of occurring. For a fair six-sided dice, each face (1 through 6) has a 1/6 probability of landing face up. For a fair spinner with equally sized sections, each section has an equal probability of being landed on. For a fair coin, heads and tails each have a 1/2 probability of appearing when flipped. The term 'fair' implies no bias or weighting toward any particular outcome.
