Understanding the Union of Subsets

This video tutorial teaches how to identify the union of two subsets using Venn diagrams and two-way frequency tables. It begins with a review of intersection and union concepts, using numbers 1 to 10 as a universal set. The tutorial explains the notation and logic behind these concepts, emphasizing the importance of not duplicating shared values. It then applies these concepts to a practical problem involving students in algebra and biology classes, demonstrating how to calculate the union using both Venn diagrams and frequency tables.
