Find B bar n C bar

Let n = intersection of two sets.

Let B bar = complement of set B.

Let C bar = complement of set C.

Let U = universal set

U = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 }

Set B = { 2, 4, 6, 7, 8 }

Set C = { 1, 3, 4, 6 }

Let me see.

B bar = { 0, 1, 3, 5, 9 }

C bar = { 0, 2, 5, 7, 8, 9 }

B bar n C bar = { 0, 5, 9 }

You say?

Perfect. It is good to know that I am right because it takes me a while to fully understand a new concept regardless of the field of study.
