Question

verify whether A=(20,22,23,24,) and B={ 25,30,40,45}are disjoint sets?​

Answer 1

Yes, A and B are disjoint sets

Definition of disjoint sets

• Two sets are said to be disjoint if they have nothing in common or there is no common elements between them.

• When we take intersection of such sets, the resulting set is an empty set.

Step-by-step explanation:

A=(20,22,23,24)

B=(25,30,40,45)

A∩B=(20,22,23,24) ∩ (25,30,40,45)

A∩B=∅ (EMPTY SET)

Since the intersection of A and B is an empty set. It is verified that A and B are disjoint sets.
