Given that P(A∪B)=0.7 and P( A ∪B)=0.9. Find P(A). Find P(B).

Given that A and B are fndependent events with
(i) P(A)=2P(B)=0.7) and P(A∩B)=0.12, find P( A ∩ B ).
(ii) P(A∪B)=0.8 and P(B)=0.25, find P(A).
(iii) P(A)=0.2 and P(B)=0.3.
Let C be the event that at least one of A or B occurs. and let D be the ovent exactly one of A or B occurs. Find P(C),P(D),P(A,D), P(D∣A). Determine whether A and D are independent.

Given that P(A)=0.3,P(B)=0.5P(A∣B)=0.4. Find P(A∩B),P(B∣A),P(A)B) and P(A∣ B ).
