I don't have a lot of experience with set theory, as I suspect this question will make clear!
As the title says, I'm interested in expressing the non-intersecting sections of three sets using a single set operation.
What I mean is, how would you express the gray shaded regions in the following Venn Diagram?
My best guess is that this has to do with complements... something like
((A ∪ B) ∪ (A ∪ C) ∪ (B ∪ C))C
...maybe? But I am concerned that this complement would also include the universe, U, which I don't want to be part of the selection. I also suspect that my notation is wrong, so apologies if that's the case.
Thanks for any help!
