If A = {1, 3, 7, 8} and B = {2, 4, 6}, then A and B are ______ .
equal sets
equivalent sets
joint sets
disjoint sets
A = {1, 3, 7, 8} and B = {2, 4, 6}
We observe that the sets A and B have no elements in common.
Hence, A and B are disjoint sets.
If A = {5, 6, 7, 8, 9, 10} and B = {4, 6, 8, 10, 12} then set A and set B are
If A = {Quadrilaterals} and B = {Rectangles}, then set A and set B are
