" (v) "(A-B)nn B=phi

Prove that : (A-B) nn (B-A)=phi .

For any two sets A and B,prove any one of the following: (A-B)nn(B-A)=phi .

A and B are two events such that P(A) ne 0 . Find P(B/A) if (i) A is a subset of B (ii) A nn B = phi

A and B are two events such that P(A)!=0 Find P(B|A) if (i) A is a subset of B (ii) A nn B=phi

If A and B are event's such that P(A | B)=P(B | A) , then A) A subset B but A ne B B) A=B C) A nn B=phi D) P(A)=P(B)

Draw a Venn diagram to represent the following three facts (i) A nn B=phi (ii) D sube B sube C and (iii) A nn D=phi

Prove that : (A-B) nn (A nn B)=phi .

If A nn C=phi, then prove that (A xx B)nn(C xx B)=phi

If A and B are two sets satisfying A-B=B-A , then which one of the following is correct? (a) A=phi(b)A nn B=phi(d) None of these (c)A=B

Let S={1,2,3,...,10} .Suppose "M" is the set of all the subsets of "S" ,then the relation [R={(A,B):A nn B!=phi,A,B in M} is
