The intersection of two sets, A and B, is a new set, let's call it C, which contains the elements that were in both A and B.

The intersection of two sets, A and B, is a new set, let's call it C, which contains the elements that were in both A and B. Example: Set A: {1,2,3} Set B: {2,3,5} Set C: {2,3}
