How to venn diagrams with three diagrams

The video tutorial explains set theory concepts, focusing on universal sets, subsets, intersections, and unions. It introduces a universal set and subsets A, B, and C, and demonstrates how to find intersections and unions among these sets using set notation. The tutorial emphasizes the difference between intersection and union, providing examples to illustrate these concepts.

What numbers are included in the universal set U?

• None of the above

• 3, 1, 4, 2, 5

• 2, 5, 8

• 1, 2, 3, 4, 5, 6, 7, 8, 14

Which numbers are common in both sets B and C?

• 2 and 5

• None of the above

• 3 and 4

• 1 and 8

What is the result of A intersect B intersect C?

• 2

• 3

• 8

• 5

What elements are included in A Union B Union C?

• 1, 2, 3, 4, 5

• 2, 5, 8

• None of the above

• 3, 1, 4

What is the result of A intersect B Union C?

• None of the above

• 3, 1, 4
