If (R={(1,1),(2,2),(3,3),(1,2),(2,1)}) on (A={1,2,3}), which partition is associated with this equivalence relation?

Answer and explanation

Correct answer: ({{1,2},{3}})

Step 1: (1) and (2) are related because ((1,2)) and ((2,1)) are present. Step 2: (3) is related only to itself. Step 3: Hence the classes are ({1,2}) and ({3}).
