Study Plan
Learn the Theory
Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Basic idea of probability, 2. Experimental probability and coin toss data, 3. Sample space, elementary events, and mutually exclusive events.
Practise
Solve the textbook exercises and extra practice questions. There are 43 questions available for this chapter.
Revise & Test
Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.
Spaced Revision
Come back to Probability after a week. Use flashcards for quick recall and try past exam questions on this chapter.
What to Focus On
- Probability is a numerical measure of chance.
- Random experiment: result is uncertain, but possible outcomes are known.
- Experimental probability uses actual trials.
- Equally likely outcomes have equal chance of occurrence.
- Sample space is the set of all possible outcomes.
- For one coin toss, the sample space is {H, T}.
- Experimental probability is an estimate from actual data.
- More trials usually give a more stable probability.
- For a fair coin, the theoretical probability of head is 1/2.
Common Mistakes to Avoid
Tossing two coins has only three equally likely outcomes: two heads, two tails, or one of each.
When a die is thrown, odd and even are the two equally likely outcomes, so each has probability 1/2 without checking the six faces.
A complementary event means simply 'the other event' even if the two events do not cover all outcomes or overlap.
