30.[A-(B-A)]uu[B-(A-B)]=

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}

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

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

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

If A and B are two sets ,then (A-B)uu(B-A)uu(AnnB) equals

If A and B are two sets ,then (A-B)uu(B-A)uu(AnnB) equals

If A and B are two sets ,then (A-B)uu(B-A)uu(AnnB) equals

If A and B are two sets ,then (A-B)uu(B-A)uu(AnnB) equals

Which of the following are corect: 1. A-B=A - (Ann B) 2. A = (A nnB) uu (A-B) 3. A - (B uu C) =(A-B) uu (A-C)
