More, less, and equally likely
key notes :
🌟 What does “Likely” mean?
- “Likely” means how much something can happen.
- It tells us if something is easy or hard to happen.
🔵 More Likely
Something is more likely if it has a greater chance of happening.
Example:
- A bag has 8 red balls and 2 blue balls → picking red is more likely.
🟢 Less Likely
Something is less likely if it has a smaller chance of happening.
Example:
- A bag has 1 green ball and 9 yellow balls → picking green is less likely.
🟡 Equally Likely
Things are equally likely when they have the same chance.
Example:
- A coin has heads and tails → both are equally likely.
