Prove from the basic rules thatPr(A) + Pre-A) = 1. 3 Multiplying. Prove from the definition of statistical independence that if 0 Pr(A), and0 Pr(B), and A and B are statistically independent,Pr(A&B) = Pr(A)Pr(B).4 Conventions. In Chapter 4, page 40, we said that the rules for normality andcertainty are just conventions.
