Question: 2. For three events A, B, C, we have A (B C) = (A B) (A C). (1.1) and A (B C) = (A B)

2. For three events A, B, C, we have A (B C) = (A B) (A C). (1.1) and A (B C) = (A B) (A C). (1.2) Using the above equations (1.1) and (1.2), prove the following: (a) A = (A B) (A Bc). (b) (A B) and (A Bc) are disjoint, that is (A B) (A Bc) = (c) P (A) = P (A B) + P (A Bc).
