3.symmetric
Work Step by Step
Assume
set of all webpages
I) If a person has visited webpage A then he has visited webpage. So,
for every element in A. Thus, the relation is reflexive.
It is possible that some people has visited webpage B but not has visited webpage A. So, the relation is not symmetric.
If everyone who has visited webpage A has also visited webpage B and If everyone who has visited webpage B has also visited webpage A, then these webpages are equal. So, the relation is not antisymmetric.
If everyone who has visited webpage A has also visited webpage B and If everyone who has visited webpage B has also visited webpage C, then everyone who has visited webpage A has also visited webpage ns C. Thus, the relation is transitive.
symmetric
