Consider following relations on the set of positive integer: R₁ = {(a,b) | a> b} R₂ = {(a,b) | a = b + 3} R3 = {(a,b) | a+b>4} a) Which of these relations are symmetric and why? If not symmetric give counter example. b) Which of these relations are reflexive and why? If not symmetric give counter example.
