Find the union of two sets including null set

The video tutorial introduces the concept of sets, using unconventional examples to illustrate that set elements can be diverse, not just numbers or letters. It describes set A with various elements and explains the concept of a null or empty set using set B. The tutorial then focuses on finding the union of two sets, emphasizing that the union includes all elements from both sets, or just one if the other is empty. The explanation clarifies that union is not the same as intersection, as it includes elements from either or both sets.
