Let P(E) denote the probability of occurrence of event E. If A and B are two events associated with an experiment such that `|[P(A)-1,P(B),-P(A nn B)],[P(B),-P(A nn B),P(A)-1],[-P(A nn B),P(A)-1,P(B)]|=0` then
(A) `P(A uu B)=1`
(B) `P(A/B)=(P(A)+P(B)-1)/(P(B))`
(C) if `A sub B` then `P(B)=P(A uu B)`
(D) if `A sub B` then `P(A)=1`
