Pr add split by complement

Pr_add_split_by_complement

Mathematical statement

Law of Total Probability (Partitioning an Event) The probability of an event f r occurring can be calculated by summing the probabilities of two disjoint cases: 1. f r occurs AND g r occurs. 2. f r occurs AND g r does NOT occur. Good to be used with Pr_multi_let_equiv_single_let

Mathematical statement

Monotonicity of Probability If event A (defined by predicate f) implies event B (defined by predicate g) for all outcomes r, then the probability of A is less than or equal to the probability of B.
