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.

1 If the water is still cool after the first couple minutes, increase the length of each session to 1.5 or 2 minutes. 2  The total amount of time depends on your microwave's power and the amount of water you're boiling. 3  Don't expect a rolling boil in a microwave. If the recipe would take less than 20 minutes to boil at sea level, add 1 minute of cooking time for each 1,000 ft (305m) above sea level. 2  If the recipe would take more than 20 minutes to boil at sea level, add 2 minutes for each 1,000 ft (305m) above sea level.
