Assume we are given set A = {1, 2, 3, 4, 6, 12} and relation, R, from A x A. The relation is stated as follows:
R = {(a, b) | a divides b} where (a, b) are elements of A x A.
a) Mention all the ordered pairs (a, b) that are elements of the relation.
b) Employ the results from part a to construct the corresponding zero-one matrix.
