# Continue Instruction

1. 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.
2. Introduce mutually exclusive events and how to solve for these events.
3. Introduce more real-world examples of conditional probability, using tree diagrams.
4. Introduce key terms.
Frequency table
Relative frequency
Tree diagram
5. 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 these problems can be used to demonstrate compound probability, sample space, and outcomes.

Use this Khan Academy video to demonstrate the addition rule for probability (11 minutes).

Check for prior understanding using this CCSS 8th grade exercise on frequency tables.

Have students enter their observations (what they learned, what they need to learn, etc) in their Daily Learning Logs. If appropriate, use a prompt: What surprises them about probability?
