🔑 Key Concepts
- Theoretical probability is the probability based on equally likely outcomes.
- Experimental probability is based on actual results collected during an experiment.
- Experimental results may differ from theoretical results.
- The more trials performed, the closer experimental probability often gets to theoretical probability.
- Tables and simulations can help compare expected and actual outcomes.
✏️ Worked Examples
🧠 Math Vocabulary
- Probability: The likelihood that an event will occur.
- Theoretical Probability: The probability based on reasoning and equally likely outcomes.
- Experimental Probability: The probability based on collected data from an experiment.
- Outcome: A possible result of an experiment.
- Trial: One repetition of an experiment.
💡 Main Idea
Theoretical probability tells what should happen, while experimental probability tells what actually happened. Comparing the two helps students understand variation in real-world probability experiments.
📚 What You Should Already Know
Students should be comfortable working with fractions, basic probability, and interpreting tables.
🚀 What Comes Next
Students can extend these ideas by comparing larger sample sizes and investigating how simulations approach theoretical probability over time.
