So, as R is reflexive, symmetric and transitive, hence, R is an Equivalence Relation. Let us see the example Voting Paradox: there are 3 candidates for election. For relation, R, an ordered pair (x,y) can be found where x and y are whole numbers and x is divisible by y. a Since y = (x + a)(x + b), and y also equals x2 + (a + b)x + ab, then those two quantities must be equal to each other! For property 1, probably the most trivial answer is the empty relation on the set of all people — i.e., “absolutely no two people are in this relation”. In logic and mathematics, transitivity is a property of a binary relation.It is a prerequisite of a equivalence relation and of a partial order.. The intersection of two transitive relations is always transitive. Let us assume that R be a relation on the set of ordered pairs of positive integers such that ((a, b), (c, d))∈ R if and only if ad=bc. Therefore, xRx holds for all ‘x’ in A.
