Problem2: A) Let A and B be two events such that: P(B) = 0.3, P(A UB) = 0.7. Answer to the following questions: 1) Compute P(A - B). 2) If P(An B) = 0.1, what is P(A) ? 3) Compute P[(An B) "]. 4) Compute P(Acn BC). B) Let A, B, C be some events. Show the following identities. A mathematical derivation is required, but you can use diagrams to guide your thinking. 1) P(AUBUC) = P(A) + P(B) + P(C) - P(AnB) -P(BnC) -P(AnC) +P(An BnC). 2) P(AUBUC) = P(B) +P(AnB) + P(Cn Acn BC) C) Let A and B be two events. Use the axioms of probability to prove the following: 1) P(An B) > P(A) + P(B) - 1. 2) P(An BnC) > P(A) + P(B) + P(C) - 2. 3) The probability that one and only one of the events A or B occurs is P(A) + P(B) - 2P(An B)
