Question:
Probability Laws:
1. For any event A, the probability of A is between zero and one. That is, 0 <= P(A) <= 1.
2. If A and B are mutually exclusive events, then P(A or B) = P(A) + P(B). 3. If A and B are independent events, then P(A and B) = P(A) x P(B).
4. (Version 1) For any events A and B, P(BIA) = P(A and B)/P(A).
5. (Version 2) For any events A and B. P(A and B)= P(A) x P(BIA).
If P(A/B) 4 and P(B) = .6, then P(AB) = .667.
