" (ii) "A-(A-B)=A nn B

For any two sets A and B prove the following: A-(A-B)=A nn B

Which one of the following is correct? a A uu(B-C)=A nn(B nn C') b) A-(B uu C)=(A nn B')nn C' c) A-(B nn C)=(A nn B')nn Cd)A nn(B-C)=(A nn B)nn C

A-B is equal to a.(A uu B)-(A nn B), b.A nn B^(C), c.A nn B,d.B-A

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

If A and B are two sets,then (A-B)uu(B-A)uu(A nn B) is equal to A uu B( b) A nn B( c) A (d) B

For any two events A and B associated to a random experiment,prove that: P(A)=P(A nn B)+(A nnbar(B))P(B)=P(A nn B)+(bar(A)nn B)P(A uu B)=P(A nn B)+(A nnbar(B))+P(bar(A)nn B)

Applying the axiom of equality of two sets prove the identiti for any two sets A and B. A nn (A' uu B) = A nn B

Consider the following equations a) A-B=A-(A nn B) b) A=(A nn B)uu(A-B) c) A-(B uu C)=(A-B)uu(A-C) Which of these is / are correct

Using various laws on operations on sets prove the following : A nn (A nn B)= A nn B

Prove any one of the following: Ann(A' uu B)=A nn B
