A Relation R is defined on a set A where A = set of age of each family member e.g (4, 12, 14, 19, 21).
1. Which order pairs are in the relation R if a>b? Make a set with name R1.
2. Draw the graph of this relation R1.
3. Is this relation R1 symmetric? Why and Why not?
4. Is this relation transitive? If not then add minimum number of ordered pairs in R so that it becomes a transitive relation. Draw the graph of the new relation.
5. Add minimum number of ordered pairs in R1 so that it becomes reflexive.
