Probability

🔹 What Is It?

Probability is the math of chance — it tells us how likely something is to happen.

🧩 Clue to Remember

If something can happen, we can find the probability it will happen.

🔹 Example

If you flip a coin:

• The chance of heads is one out of two.
  We write it as:
  
  

• Probability = one over two
  
  

• Or in words: one-half chance
  
  

💡 Why It Matters

Probability helps with planning, games, weather forecasting, science experiments, and even making decisions with risk.
