Probability Model

Probability model: A model that lists all possible outcomes of a probability experiment and must satisfy the two rules of probability.

P(E): The probability of Event E.

Rules of Probability

  1. The probability of an event is between 0 and 1; 0 ≤ P(E) ≤ 1.
  2. The sum of the probabilities of all outcomes must equal 1; S = {e_1,...,e_n}, then P(e_1+...+e_n ) = 1.

A probability model lists all possible outcomes of a probability experiment and must satisfy the two rules of probability listed above. With respect to notation, P(E) means the probability of Event E.
