Question

The following applies to questions 1-3 below. Assume the following notation: p(A) is the probability of event A; p(AB) is the probability of A and B; P(A V B) is the probability of A or B: p(AB) is the probability of A given B; S is the universe of possibilities; -A is the negation of A: and is the null event 1. If and only if p(A V B) p(A) + p(B), p(AB) ;r where r is A. 1 B. 0.5 C. 0 E. 0.25 2. p(S) where r is A. 0.5 B. 0 C. V2 D. 0.75 E. 1 3. For all A in S, p(A) where r is A. 0.75 B. 1 C. 0 D. V2 E. 0.5
