If (A={1,2,3}) and (R={(1,1),(2,3)}), which pairs must be added to make (R) reflexive?

Answer and explanation

Correct answer: ((2,2)) and ((3,3))

Step 1: Reflexivity needs ((1,1),(2,2),(3,3)). Step 2: ((1,1)) is already present in the relation. Step 3: Therefore only ((2,2)) and ((3,3)) must be added.
