So it's going to be A intersected with the relative complement of C in B and the absolute complement of that. So this is going to be the intersection of the set A and the set of all things in the universe that are neither a 0 or a blue. So it's essentially the things that satisfy both of these, that it has to be in set A and it has to be in the set of all things in the universe that are neither a 0 or a blue. So let's think about what this is. So the number 3 is in set A and it's in the set of all things in the universe that are neither a 0 or blue. So let's throw a 3 in there. The number 7, it's an A and it's in the set of all things in the universe that are neither a 0 or a blue.
