What Makes a Coin Toss Fair or Biased?

Imagine you're flipping a coin. A fair coin has an equal chance of landing on heads or tails, like it's playing a game where both sides have the same power. But if the coin is biased, one side might be heavier, making it more likely to land on that side. It’s like when one kid in a tug-of-war is stronger than the other, they're going to win more often.

  2. If you flip a coin in the air and it lands on the floor, the surface it hits can influence which side ends up face up.
  3. A magician might use a biased coin to always get the result they want.
