WebFirst, we show P ( A ∪ B) = P ( A ∪ ( B ∩ A C)). A ∪ B = ( A ∪ B) ∩ S by the identity law, where S, the sample space, is our universal set = ( A ∪ B) ∩ ( A ∪ A C) by the negation law = A ∪ ( B ∩ A C) by the distributive law Hence, A ∪ B = A ∪ ( B ∩ A C); thus, we know (1) P ( A ∪ B) = P ( A ∪ ( B ∩ A C)) 2. WebFor any A ∈B, define P(A)by P(A) = X {i:si∈A} pi. 10CHAPTER 1. PROBABILITY THEORY (The sum over an empty set is defined to be 0.) Then P is a probability function onB. This remains true if S={s1,s2,...} is a countable set. Proof: We will give the proof for finiteS. For anyA ∈B,P(A) = P i:si∈Api≥0, because everypi≥0. Thus, Axiom 1 is true. Now,

WebP (A/B) = P (A) and P (B/A) = P (B) and vice versa. If S is the sample space of the random experiment, A and B are any two events defined in this sample space. The two events A and B are said to be independent, that is If P (A / B) = P (A / B’) = P (A) or P (B / A) = P (B / A’) = P (B) and P (AB) = P (A) * P (B)
WebLet A A and B B be events in sample space S S. A A and B B are exhaustive if A\cup B=S A∪ B = S . When an event is described to you as something that could possibly happen, the complement of that event is every other possible thing that could happen.
