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

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

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

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.
