Question

let A = { 1,2,3}.Then show that the number of relations containg (1,2) &(2,3) which are reflexive,transitive but not symmetric is 3.​

Answer 1

Answer:

R = {(a, b) : a ≤ b3} Here R is set of real numbers Hence, both a and b are real numbers Check reflexive If the relation is reflexive, then (a, a) ∈ R i.e. a ≤ a3 Let us check Hence, a ≤ a3 is not true for all values of a.
