Question
If A = {1, 2, 4}, B = {2, 4, 5} and C = {2, 5}, write (A - C) × (B - C).
✓
Answer
We have,
A = {1, 2, 4}, B = {2, 4, 5} and C = {2, 5}
$\therefore$ A - C = {1, 2, 4} - {2, 5}
A - C = {1, 4}
and, B - C = {2, 4, 5} - {2, 5}
B - C = {4}
Now,
(A - C) × (B - C) = {1, 4} × {4}
(A - C) × (B - C) = {(1, 4), (4, 4)}
