What are the relationship among set?

Answer 1

The possible relationships between two sets (here arbitrarily named A and B) are:

• If each element of set A is also element of set B (and vice versa), the two sets are equal.
• If no element of set A is element of set B (and vice versa), the two sets are disjoint.
• If all elements of set A are also elements of set B, the set A is a subset of set B. If set B contains elements not found in set A, the set A is a proper or strict subset of set B. Set B is called supersetresp. proper superset of A.
• If set A and set B share some elements, but each set also has elements not found in the other set, the two sets intersect.

Answer 2

There are many different relationships that may take place among a set. These relationships might be patterns that you witness for example.
