Web27 apr. 2024 · Approach: The given problem can be solved based on the following observations: Considering an antisymmetric relation R on set S, say a, b ∈ A with a ≠ b, then relation R must not contain both (a, b) and (b, a).It may contain one of the ordered pairs or neither of them. There are 3 possible choices for all pairs.; Therefore, the count … WebSince ˚ˆA X A, the set R = ˚is a relation on A. Is R re exive?Symmetric? Transitive? If a property does not hold, say why. Solution: The relation is valid. Let A= fa,b,cg; since (a,a),(b,b),(c,c) 2=˚So the relation is not re exive. There is no relation between a and b and b and a (hence symmetric). Also there is no relation between a and b ...
