Key Topics to Revise
1. What Probability Means
- Probability is a measure of how likely an event is to happen.
- It is used for random events, where the exact outcome cannot be known in advance.
- Random situations include tossing a coin, rolling a die, and a lucky draw.
2. Subjective Probability and Randomness
- People sometimes predict probability using personal judgement or present conditions.
- Two friends may give different predictions about rain based on the same situation.
- Randomness means all possible outcomes are known, but the exact outcome cannot be predicted.
3. Experimental Probability
- Experimental probability is found from actual trials or statistical data.
- It is also called relative frequency.
- It is useful when results come from observation rather than pure reasoning.
4. Theoretical Probability
- Theoretical probability is used in a perfectly fair situation.
- It assumes all possible outcomes are equally likely.
- It is based on favourable outcomes and possible outcomes, not on actual experiments.
