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)

A = (A nn B) uu (AB) and A uu (BA) = (A uu B)

A - (B uu C) equals :

A uu B = (AB) uu (BA) uu (A nn B)

Consider the following for any three non-empty sets, A, B and C. 1. A-(BuuC)=(A-B)uu(A-C) 2. A-B=A-(AnnB) 3.A=(AnnB)uu(A-B) Which of the above is/are correct ?

(A uu B) nn (A uu B ^ (c)) = A

A-(B uu C) equals
