If A = {2, 3, 4, 5) and B = {3, 6, 7, 10} and R is a relation defined by
R = {(a, b): a is relatively prime to b, a e A and b E B}, then find in Roster form.
Also find its domain and range.

Answer:
The relation R in roster form is:
R = {(2, 3), (2, 7), (2, 10), (3, 3), (3, 6), (3, 7 (4, 3), (4, 7), (5, 3), (5, 10)}
The domain of R is the set A = {2, 3, 4, 5}.
The range of R is the set B = {3, 6, 7, 10}.
