Question

Given the following sets:

A={ 2, 4, 6, 8, 10}
B={ 3, 5, 7, 9}
C={ 2, 3, 5, 7}
N={ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Match the following Unions and intersections to the correct set.

1.
What is A U C?

2.
What is A ∩ B?

3.
What is A ∩ N?

4.
What is B ∩ N?

5.
What is B U C?

{2, 3, 4, 5, 6, 7, 8, 10}


{2, 3, 5, 7, 9}


{ }


{3, 5, 7, 9}


{2, 4, 6, 8, 10}

Answer 1

A = {2, 4, 6, 8, 10}
B = {3, 5, 7, 9}
C = {2, 3, 5, 7}
N = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

1. A ∪ C = {2; 3; 4; 5; 6; 7; 8; 10}
2. A ∩ B = { } =Ø
3. A ∩ N = {2; 4; 6; 8; 10} = A
4. B ∩ N = {3; 5; 7; 9} =B
5. B ∪ C = {2; 3; 5; 7; 9}
