Exercise 13.1 - Probability
This exercise focuses on calculating probabilities of various events involving dice, cards, coins, and word selections using fundamental probability concepts.
Exercise 13.1 provides practice problems that help students understand basic probability concepts including sample space, favorable outcomes, and probability calculations using the formula \( P(A) = \frac{n(A)}{n(S)} \).
The exercise covers probability calculations for dice rolls, card selections, coin tosses, and word problems, along with complementary probability concepts (\( P(A') = 1 - P(A) \)).
Key Topics Covered
- Probability of events with dice (single and pair)
- Probability with playing cards
- Probability with coin tosses combined with dice
- Word selection probability problems
- Complementary probability concepts
- Sample space determination
Important Note:
Remember that probability values always range between 0 and 1, where 0 indicates an impossible event and 1 indicates a certain event. The sum of probabilities of all possible outcomes in a sample space equals 1.
