Probability

The chance of something tells us how likely it is to happen. We can show different chances on a line, from impossible to certain.

• Impossible: It can never happen.
  Example: Riding a dinosaur.
• Unlikely (or Less Likely): It probably will not happen.
  Example: Rolling a die and getting a 3.
• Even Chance: It has an equal chance of happening or not happening.
  Example: Tossing a coin and getting heads.
• Likely (or Most Likely): It probably will happen.
  Example: Drinking something today.
• Certain: It must happen.
  Example: The sun will rise tomorrow.
