Probability

🔹 What Is It?

Probability is the chance that something will happen.

It’s measured on a scale from zero to one:

• Zero means it’s impossible.
  
  

• One means it’s certain.
  
  

It can also be shown as a fraction, decimal, or percent.

🧩 Clue to Remember

Probability = What you want ÷ All possible outcomes

🔹 Example

What is the probability of rolling a 3 on a six-sided die?
Only one side shows 3.
So the probability is:
One over six
Or about 0.17 or 17 percent

💡 Why It Matters

Probability helps us predict outcomes, whether in games, weather, science, or real-life decisions.
