What is the difference between union and intersection in set theory?
In set theory, the union of two sets is a set containing all elements from both sets, while the intersection contains only the elements that are common to both sets.
Can you give me an example of union and intersection?
Sure! If Set A = {1, 2, 3} and Set B = {2, 3, 4}, then the union A ∪ B = {1, 2, 3, 4} and the intersection A ∩ B = {2, 3}.
What symbols are used for union and intersection?
The symbol for union is '∪' and for intersection, it is '∩'.
