Question

Out of these by which we cannot represent symmetric difference between two sets 1) a=b 2 ) a is shaded and b is shaded but both has equal size and are apart from each other

Answer 1

Answer:

The symmetric difference using Venn diagram of two subsets A and B is a sub set of U, denoted by A △ B and is defined by

A △ B = (A – B) ∪ (B – A)

Let A and B are two sets. The symmetric difference of two sets A and B is the set (A – B) ∪ (B – A) and is denoted by A △ B.

Thus, A △ B = (A – B) ∪ (B – A) = {x : x ∉ A ∩ B}

or, A △ B = {x : [x ∈ A and x ∉ B] or [x ∈ B and x ∉ A]}
