You know that by definition, (1) P ( A ∣ B) = P ( A ∩ B) P ( B) and so if we condition everything on C having occurred, we get that. (2) P ( A ∣ ( B ∩ C)) = P ( ( A ∩ B) ∣ C) P ( B ∣ C)

The intersection of two or more sets is the set of elements … WebIfAandBare sets, thenP(A)∩ P(B) =P(A∩B). Proof:This is a set equality, so we have to proveP(A)∩P(B)⊆ P(A∩B) andP(A∩B)⊆ P(A)∩P(B). Proof ofP(A)∩P(B)⊆ P(A∩B):LetX∈ P(A)∩P(B). Then we see thatX∈ P(A) andX∈ P(B). This implies thatX ⊆AandX ⊆B. Then we see that ifz ∈X, thenz ∈Aandz ∈B, that is z∈A∩B. Hence ...

[Note: BC is another way of writing the complement of set B] There are two ways of solving set proofs like these, one is to lo ok at an arbitrary point and use the properties of sets to argue why something it true.
WebTHEOREM: 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.
