1. Let A = {0, 2, 4, 6, 8}, B = {0, 1, 2, 3, 4}, C = {0, 3, 6, 9}. Find

(a) ABC

(b) ABC

(c) (AB)C

(d) A(BC)

(e) (AB)C

2. List the elements of each set and give its cardinality.

A = {x Z + : x is an integer multiple of 3 and x < 16}

3. Define sets A, B and C as follows:

A = {2,4,6,8}

B = {x Z: x is even and 0 < x < 10}

C = {x Z: x is even and 0 < x 10}

Indicate whether each of the following statements is true or false. Justify your answer.

(a) A B

(b) A B

4. Find the power set for set A={a, b, c}
