Given:
2 sets A and B
- A = {2, 4, 6, 8}
- B = {2, 3, 5, 6}
To find:
A ∩ B = ?
Solution:
Concept used:
- ∩ is the symbol of Intersection. It's used to show the elements of the set which are common in both sets.
Lets solve this.
A ∩ B includes terms which are common in both A and B.
Here (2, 6) is common in both Set A and set B.
Therefore,
A ∩ B = {2, 6}
KNOW MORE:
- U is the symbol of Union which is used for telling all elements in sets A and B but the terms shouldn't be repeated.
- De Morgan's law states that:
(A U B)' = A' ∩ B'
