      E [F denotes the union of E and F. E \F denotes the intersection of E and F. Ec stands for the complement of E, that is E = S nE. E ˆF means that E is a subset of F. If E \F = ;, we say that E and F are disjoint. Similarly, we can talk about the union and intersection of more than two events: [n i=1E i; [1 i=1E i; \ n i=1E i; \ 1 i=1E i: 1

      The probability of an event is always between 0 and 1.? The probability of an eventand its complement is always 1. Several Events? The union of several simple events creates a compound event that occurs if one or more of the events occur.? The intersection of two or more simple events creates a compound event that occurs only if all the simple ...

      THEOREM: the union of of events. The probability that either A or B will happen or that both will happen is the probability of A happening plus the probability of B happening less the probability of the joint occurrence of A and B: P(A∪B) = P(A)+P(B)−P(A∩B) Proof.

      The union A[B of two events Aand B is an event that occurs if at least one of the events Aor B occur. The key word in the definition of the union is or. For mutually exclusive events, the probability that at least one of them occurs is P(A[C) = P(A)+P(C) For example, if the probability of event A = f3g is 1/6, and the probability of the event ...

      which is a disjoint union of sets. In fact, this can be done for infinitely many sets: ... we refer to it as a probability space and often write this as (Ω,F,P). Example 2.1. Let Ω be a countable set and let F = collection of all subsets of Ω. ... We will show that the formula µ(a,b] = …
