Question

( AUB) - A = B - A [prove using properties of set]​

Answer 1

(A U B) = A + B

(A U B) - A => means that elements of A are removed from A U B

B - A => THE ELEMENTS WHICH ARE COMMON IN BOTH A & B ARE ELIMINATED

EXAMPLE:- B = {1,2,3,4,5,6}

A = {1,2,3,4}

B - A = {1,2,3,4,5,6} - {1,2,3,4}

B - A = {5,6}

=》FROM THE DIAGRAM
