What Makes a Coin ‘Fair’ or Not?

A fair coin is one that has an equal chance of landing heads or tails, like a magic coin that doesn’t favor anyone.

Imagine you have a shiny coin, and it's like a wizard who can flip itself into the air. When it lands, it can be heads (like a smile) or tails (like a frown). A fair coin is like a wizard who loves both sides equally, so when it flips, there’s a 50% chance of heads and 50% chance of tails.

But if the coin isn’t fair, maybe it’s been cursed! It might favor one side more than the other. For example, a biased coin could land on heads 70% of the time, like a wizard who always chooses the smile over the frown.

A coin can be unfair if:

• It’s wobbly and doesn’t spin evenly.
• One side is heavier, so it lands more often on that side.
• Someone cheated by using a special coin, like a wizard with a secret spell.

So when you flip a coin, magic or not, it's all about whether the sides are treated equally, and that’s what makes a coin fair or not. A fair coin is one that has an equal chance of landing heads or tails, like a magic coin that doesn’t favor anyone.
