How to find the intersection and union with sets in a venn diagram

The video tutorial explains Venn diagrams, focusing on universal sets and subsets A and B. It details how to identify elements within these sets, using brackets for notation. The tutorial further explores the concepts of intersection and union, illustrating how to find common and combined elements between sets.

What does the universal set represent in a Venn diagram?

• The intersection of sets A and B

• Only the elements in set B

• The entire collection of elements under consideration

• A subset of set A

Which number is contained in both sets A and B?

• 2

• None of the above

• 8

• 5

What is the intersection of two sets?

• The elements that are unique to each set

• The sum of all elements in both sets

• The total number of elements in both sets

• The elements that are common to both sets

What does the union of two sets represent?

• Only the elements in set A

• The elements that are common to both sets

• Only the elements in set B

• The combination of all elements in both sets

Which of the following is the correct union of sets A and B?

• 5, 8

• 2, 8

• 2, 5, 8

• 2, 5
