Q: Relations
a) In one paragraph, explain what a relation is.
b) Create a binary relation between X and Y that contains at least 6 ordered pairs, given that X and Y are the following:
Let the set X = {Bill Smith, Amos Black, Tarra Sigorney, Alfred Ross}
Let the set Y = {MAT 102, ENG 202. PSY 303, BUS 405}
c) Given the following information, create the appropriate digraph
Let X = {1, 3, 4, 6}
Let Y = {1, 2, 3, 5, 7}
Create a digraph that describes the binary relation x < y. For example, (1,3) would be a member of the relation.
