Extension:
A ‘fair’ die, ‘fair’ spinner, and ‘fair’ coin mean that each possible outcome has an equal chance of occurring. For a fair die, each face (1 through 6) has a 1/6 probability. For a fair spinner, each section is equally likely to be landed on. For a fair coin, heads and tails each have a 1/2 probability. Fairness implies no bias or weighting toward any outcome.
