Mutually Exclusive Events
Understand that mutually exclusive events cannot happen at the same time. Learn that the sum of probabilities for all mutually exclusive outcomes is exactly 1.
About This Topic
Understand that mutually exclusive events cannot happen at the same time. Learn that the sum of probabilities for all mutually exclusive outcomes is exactly 1.
Key Questions
- What does it mean for two events to be mutually exclusive?
- How can we use the fact that all possible outcomes sum to 1 to find a missing probability?
- Why can a coin not land on both heads and tails at the same time?

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
RubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.

The Probability Scale
Map the likelihood of events onto a numerical scale from 0 to 1. Represent probabilities using fractions, decimals, and percentages.

Calculating Theoretical Probability
Calculate the exact probability of a single event happening when all outcomes are equally likely. Express these probabilities mathematically.

Experimental Probability and Relative Frequency
Conduct experiments to find the relative frequency of an event. Compare these experimental results with theoretical probabilities.
