EXTENDING THE DISCUSSION
After the observational question, randomly call on one or more students to share what they or their partner answered. Then ask the class, “Did anyone notice…?” using the suggestions above or anything else you’ve noticed.

Students might wonder:
- Why some outcomes are more likely than others
- How to find the total number of outcomes
- What happens when an event happens many times
- If probability can ever be greater than 1
- How probability works in real life

Example student responses
To the observational question, What is probability?
LOW-LEVEL
Probability is how likely an outcome is to happen.
HIGH-LEVEL
Probability is the chance that a specific outcome will happen based on the number of favorable outcomes compared to the total number of outcomes.
