In-text Questions

Answer: A coin toss is considered fair because a fair coin has two equally likely outcomes (Heads or Tails), each with a 50% probability. The result is random and unpredictable, ensuring neither team has an unfair advantage, and the single outcome provides a clear decision.

- A coin toss is considered a fair method because a fair coin has two possible outcomes: Heads or Tails.
- For a fair coin, the probability of getting Heads is 1/2 (50%), and the probability of getting Tails is also 1/2 (50%).
- This means both teams have an equal chance of winning the toss.
- The outcome of a coin toss is random and cannot be predicted beforehand, ensuring that neither team has an unfair advantage.
- Only one outcome occurs during a toss, making the decision clear and unambiguous.
