- Introduce compound probability and demonstrate the difference between dependent and independent events. Show examples of independent events and the formula to use when solving these types of problems.
- Introduce mutually exclusive events and how to solve for these events.
- Introduce more real-world examples of conditional probability, using tree diagrams.
Tree diagram .
- Have students work individually or in pairs to solve probability problems. Students can hand in results for grading or use as a discussion tool.
Tips and Tools
Either of thesecan be used to demonstrate compound probability, sample space, and outcomes.
UseKhan Academy video to demonstrate the addition rule for probability (11 minutes).
Check for prior understanding using this CCSS 8th grade exercise on.
Have students enter their observations (what they learned, what they need to learn, etc) in their. If appropriate, use a prompt: What surprises them about probability?
