Key Topics to Revise

1

Introduction to Probability

  • Probability quantifies the likelihood of an event occurring
  • Words like 'probably', 'likely', 'possibly' can be given numerical values
  • Events that happen once don't necessarily happen every time
2

Experimental vs Theoretical Probability

  • Experimental probability is based on actual trials and observations
  • As number of trials increases, experimental probability approaches theoretical probability
  • Historical experiments: Buffon (4040 tosses), Kerrich (10000 tosses), Pearson (24000 tosses)
3

Sample Space and Events

  • Sample space contains all possible outcomes of an experiment
  • Events are subsets of the sample space
  • Elementary events have only one outcome
4

Properties of Probability

  • Probability of any event lies between 0 and 1: 0 ≤ P(E) ≤ 1
  • Sum of probabilities of all elementary events equals 1
  • Probability of impossible event is 0
