Topics in Probability

1

Events and Sample Space

  • An event is any subset of a sample space S
  • Sample space S contains all possible outcomes of an experiment
  • Events can be classified as impossible, sure, simple, or compound
2

Types of Events and Event Operations

  • Complementary event A' represents 'not A' and equals S - A
  • Union A ∪ B represents 'A or B' - occurrence of at least one event
  • Intersection A ∩ B represents 'A and B' - occurrence of both events
3

Axiomatic Approach to Probability

  • Probability is a real-valued function P with domain as power set of S and range [0, 1]
  • Three fundamental axioms define probability: non-negativity, normalization, and additivity
  • For equally likely outcomes, P(ωᵢ) = 1/n where n is total number of outcomes
4

Probability Rules and Formulas

  • Addition rule: P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
  • For mutually exclusive events: P(A ∪ B) = P(A) + P(B)
  • Complement rule: P(A') = 1 - P(A)
