Set theory counterexample

394 views

Hello everyone, can someone please help me with the set theory question

(AB)C =A(BC)

I did a Venn diagram and I see that they’re not the same and now I need to do a proof by counter example. Any ideas where and how would do I start and do a set up for that?

Thank you

What part of your Venn diagram is different?

Then write, suppose x is in … (That part of the Venn diagram).

Then show that x is not in the other side.
