Question

The symmetric difference of set A and B is denoted by ________________.

• A. A-B
• B. A$△$B
• C. A$\Theta$B
• D. A - A

Answer 1

The correct option is B A$△$B

The symmetric difference of set A and B is denoted by A △ B.

The symmetric difference of two sets A and B is the set (A – B) ∪ (B – A) and is denoted by A △B. A △B is the set of all those elements which belongs either to A or to B but not to both.

The symmetric difference, also known as the disjunctive union, of two sets is the set of elements which are in either of the sets and not in their intersection. The symmetric difference of the sets A and B is commonly denoted by.
