Thread: Sets Help III.

And please check these:

3) [(A-B)' - C]'
[({0,2,3,4})' - C]'
[({1,5})- {2,4,5}]'
[{1}]'
= {0,2,3,4,5}

4)
(A∩C)∩ B'
({2})∩{2,3,5}
= {2}

Are they correct?

[({1, 2, 3} - {0, 1, 4})' - {2, 4, 5}]' = [{2, 3}' - {2, 4, 5}]' = [{0, 1, 4, 5} - {2, 4, 5}]' = {0, 1}' = {2, 3, 4, 5}
