7. Let A = {0, 1, 2, 3, 4, 5} B = {0, 1, 5, 6, 9} C = {0, 2, 6, 7, 8}
Find A ∩ B ∩ C
8. Let A = {1, 2, 3, 4, 5, 6, 7} B = {1, 3, 5, 7, 9} C = {0, 2, 4, 6, 8, 10}
Find (A U B) - C
9. Given A = {positive whole numbers less than 20}, B = {odd numbers},
Find A - B
10. Given A = {1, 8, 9}, B = {2, 3, 4} and C = {5, 6, 7}
What is the universal set?
7.A ∩ B ∩ C = (0,2,5)
8.(A U B) - C = (1,2,3,4,5,6,7,9,10)
9.i don't know the answer
10.U = (1,2,3,4,5,6,7,8,9)
hope it helps
