Key Topics to Revise

1

1. Basic Ideas: Experiment, Random Experiment, Sample Space, and Event

  • An experiment is an operation that produces well-defined outcomes.
  • A random experiment has more than one possible outcome, and the outcome cannot be predicted in advance.
  • The sample space is the set of all possible outcomes of a random experiment and is denoted by S.
2

2. Types of Events

  • Sure/Certain event is the whole sample space.
  • Impossible event is the empty set phi.
  • An elementary or simple event has exactly one element.
3

3. Classical and Axiomatic Approaches to Probability

  • The classical approach is used when outcomes are equally likely.
  • The axiomatic approach defines probability as a real-valued function on the power set of S with range [0,1].
  • In the axiomatic approach, P(E) is always non-negative and P(S) = 1.

4. Card Facts and Standard Deck Information

  • A standard deck has 52 cards.
  • There are 4 suits: Spades, Hearts, Clubs, Diamonds.
