GIVEN:

A = { 0, 1, 2, 3, 4 }

B = { 0, 2, 4, 6, 8 }

C = { 1, 3, 5, 7, 9 }

QUESTIONS & ANSWERS:

1.）A U B U C =  { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 }

Cardinality =  10

2.) A ∩ B = { 2, 4 }

Cardinality =  2

3.）B ∩ C = { ∅ }

Cardinality =  0

4.）A ∩ B ∩ C = { ∅ }

Cardinality =  0

5.）A' =  { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 }

Cardinality =  10

6.）B' =  { 1, 3, 5, 7, 9 }

Cardinality =  5

7.) (A U B)' = { 9 }

Cardinality =  1

8.）A—B' =  { 0, 2, 3, 4, 5, 6, 7, 8, 9 }

Cardinality = 9

Hope it helps :)
