2. A ={x / x is an even number less than 15}
B = {x / x is the first seven odd number}
C = {4, 8, 12}
D = {1, 3, 5}
E = {x / x is a counting number between 1
and 2}

3. 1.What is the cardinality of A?
n(A) = 7

4. 2. Give the elements of A.
A = {2, 4, 6, 8, 10, 12, 14}

5. 3. Give the elements of B.
B = {1, 3, 5, 7, 9, 11, 13}

6. 4. Which set or sets is/are infinite?
Set E.

7. 5. Which set is an empty set?
E = { }
Because there is no counting
number between 1 and 2.

8. 6. Which sets are equal?
None.

9. 7. Is C = D? Why?
No. Because their elements
are not the same.

10. 8. Which set is equivalent to B?
Why?
Set B. Because they have the
same cardinality.

11. 9. C is a proper subset ⊂ to
what set?
Set A. Because all elements
in C are contained in A.

12. 10. B is a proper superset to
what set?
Set D, since all elements in
D are contained in B.

13. 11. Give the universal set.
U = {x / x is a counting number less
than 15}

14. 1.What is the cardinality of A?
2.Give the elements of A.
