🔑 Key Concepts
- Theoretical probability is what should happen based on all possible outcomes.
- Experimental probability is what actually happens when an experiment is performed.
- Rolling two dice creates a compound event because two independent events happen together.
- A sample space helps organize all possible outcomes.
- Experimental results may not match theoretical probability exactly, especially with a small number of trials.
✏️ Worked Examples
🧠 Math Vocabulary
- Theoretical Probability: Probability based on what should happen mathematically.
- Experimental Probability: Probability based on what actually happens during trials.
- Compound Event: An event made of two or more simple events.
- Independent Events: Events where one outcome does not affect the other.
- Sample Space: The set of all possible outcomes.
- Outcome: A single result of an experiment.
- Trial: One performance of a probability experiment.
- Pair of Dice: Two dice rolled together, creating 36 possible ordered outcomes.
💡 Main Idea
In this lesson, students compare theoretical and experimental probability by rolling a pair of dice. They learn that rolling two dice creates a compound event with 36 possible outcomes, and that experimental results may differ from theoretical expectations.
📚 What You Should Already Know
Students should understand basic probability, fractions, outcomes, sample spaces, and how to multiply probabilities for independent events.
🚀 What Comes Next
After comparing theoretical and experimental probability with dice, students can explore larger simulations, use organized lists or tables, and analyze how experimental results get closer to theoretical probability as the number of trials increases.
