GDB Question:
A = {6, 11} and B = {4, 7, 10} Find A x B
Define R1 and R2 from A to B as follows:
R1 = {(a, b) ϵ A x B |a < b}
R2 = {(a, b) ϵ A x B |a +b < 17}
Determine ordered pairs of each relation
Solution:
A X B = {(6, 4), (6, 7), (6, 10), (11, 4), (11, 7), (11, 10)}
R1 Ordered Pairs = {(6, 7), (6, 10)}
R2 Ordered Pairs = {(6, 4), (6, 7), (6, 10), (11, 4)}
