Exercise 13.2 - Probability
This exercise focuses on calculating relative frequency, expected frequency, and solving probability problems using theoretical and experimental approaches.
Exercise 13.2 provides practice problems that help students understand the concepts of relative frequency, expected frequency, and probability calculations through various real-world scenarios.
The exercise covers calculating relative frequencies from frequency distributions, finding expected frequencies using probability formulas, and solving probability problems involving dice, coins, and other random experiments.
Key Topics Covered
- Calculation of relative frequency from frequency tables
- Finding expected frequencies using probability
- Probability problems involving dice and coins
- Percentage calculations from survey data
- Application of probability formulas in real-world scenarios
Important Note:
Remember that relative frequency is calculated as frequency divided by total frequency, while expected frequency is calculated as total trials multiplied by the probability of the event.
