[2 marks]2.
Explain why the notation A ∩ B = B ∩ A is correct or incorrect. Provide an example if incorrect.
[3 marks]3.
A set A is represented by the notation A = {x | x is a positive integer less than 5}. Which of the following is NOT correct? (a) x ∈ A if x=3, (b) 6 ∈ A, (c) A = {1,2,3,4}.

4.
In a Venn Diagram, a student writes A = {x | x ∈ universe, x > 0}. What is the mistake if the diagram shows A as the entire universe?
[2 marks]5.
Construct a Venn Diagram to represent the sets: A = {2,4,6}, B = {4,5,6}. Identify A ∩ B.
[3 marks]6.
A student incorrectly writes A ∪ B = A + B. Identify the misconception and correct it.
[2 marks]7.
Given A = {x | x is a multiple of 3} and B = {x | x is a multiple of 4}, find A ∩ B and explain the notation used.
[3 marks]8.
A set C is incorrectly written as C = {x | x > 0 and x < 5}. What is a common mistake when writing set notation, and how can it be fixed?
[2 marks]9.
Using set notation, express the complement of set A = {1,2,3} within the universal set U = {1,2,3,4,5}.
[2 marks]10.
Identify and correct the error: A ∩ B = {x | x ∈ A and x ∈ B}.
[2 marks]11.
A Venn Diagram shows set A with elements {1,2,3} and set B with elements {3,4,5}. What is A ∪ B and how do you represent it in set notation?
