Topics in Probability 1
Basic Definitions and Sample Space
- Random experiment: An operation whose outcome cannot be predicted with certainty
- Sample space (S): Set of all possible outcomes of a random experiment
- Event: A subset of the sample space
Types of Events
- Complementary events: A and A' where A' = S - A
- Mutually exclusive events: A ∩ B = φ (empty set)
- Exhaustive events: E₁ ∪ E₂ ∪ ... ∪ Eₙ = S
Axiomatic Approach to Probability
- Axiom 1: P(E) ≥ 0 for any event E
- Axiom 2: P(S) = 1 where S is sample space
- Axiom 3: For mutually exclusive events E and F, P(E ∪ F) = P(E) + P(F)
Classical Probability Problems
- Coin tossing: S = {H, T} for one coin, S = {HH, HT, TH, TT} for two coins
- Dice rolling: S = {1, 2, 3, 4, 5, 6} for one dice
- Card drawing: Standard deck has 52 cards (13 each of 4 suits)
