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

the symmetric difference of A and B is not equal to (A-B)nn(B-A)(A-B)uu(B-A)(A uu B)-(A nn B){(A uu B)-A}uu{A nn B}

Which of the following statement is false: A-B=A nn B b.A-B=A-(A nn B) c.A-B=A-B' d.A-B=(A uu B)-B

Show that : (A uu B)-(A nn B) = (A -B) uu (B-A) .

For any tow sets A and B(A-B)uu(B-A)=(A-B)uu Ab(B-A)uu Bc*(A uu B)-(A nn B)d(A uu B)nn(A nn B)

If A o* B are two events then P{(A nnbar(B))uu(bar(A)nn B)}=(i)P(A uu B)-P(A nn B)(ii)P(A uu B)+P(A nn B)( iii) P(A)+P(B)(iv)P(A)+P(B)+P(A nn B)

If A and B are two sets then (A-B)uu(B-A)=(A uu B)-(A nn B)

Let A and B be sets. If A nn X = B nn X =phi and A uu X = B uu X for some set X, show that A = B. (Hints A = A nn (A uu X) , B=B nn (B uu X) and use Distributive law )

For any two sets A and B, prove that : (A-B) uu (B-A) = (A uu B)- (A nn B) .
