Exploring Venn Diagrams in IB Math Studies

What is a Venn diagram used for?

• To represent sets and their relationships visually

• To solve algebraic equations

• To draw geometric shapes

• To calculate probabilities

In a Venn diagram, what does the universal set (U) represent?

• The intersection of sets A and B

• Only the elements in set A

• All elements in the universe

• Only the elements in set B

What is the complement of a set A (A')?

• Elements in neither set A nor B

• Elements not in set A

• Elements in set A

• Elements in both sets A and B

How is the intersection of sets A and B represented in notation?

• A ∩ B

• A + B

• A ∪ B

• A - B

What does the union of sets A and B include?

• All elements in either set A or set B or both

• Only elements in set A

• Only elements in both sets A and B

• Only elements in set B

What does the complement of set B (B') represent?

• Elements not in set B

• Elements in set B

• Elements in both sets A and B

• Elements in neither set A nor B

If a Venn diagram has two sets A and B, what does the area outside both sets represent?

• Elements in both sets A and B

• Elements in set A

• Elements in set B

• Elements not in sets A or B

In the example problem, which numbers are in the intersection of sets A and B?

• 5 and 7

• 2 and 4

• 1 and 6

• 3 and 8

In the example problem, which numbers are only in set A?

• 2 and 4

• 1 and 6

• 3 and 8

• 5 and 7

In the example problem, which number is outside both sets A and B?

• 7

• 8

• 3

• 6
