Find B^c ∩ C^c

Given U = {0, 1, 2, 3, 4, 5}, B = {2, 3, 4}, and C = {1, 3, 4, 6}, find
B^c ∩ C^c.

B^c = {0, 1, 5}

C^c = {0, 2, 5}

B^c ∩ C^c = {0, 1, 5} ∩ {0, 2, 5}

B^c ∩ C^c = {0, 5}

I believe this to be true.

Re: Find B^c ∩ C^c

Yes, that's ok.  But you have typed

C = {1, 3, 4, 6}

  That 6  cannot be an element as it's not in the universe.  Fortunately it doesn't effect your answer.

Really? Why does 6 not effect my answer? That's a bit weird.

Re: Find B^c ∩ C^c

As C complement is the elements not in C 6 doesn't feature whether it's there or not.  But If you change 6 to 0 for example it would change the answer.
