1. 1E = {1, 2, 3, ..., 15}
2. 2A = {even numbers} = {2, 4, 6, 8, 10, 12, 14}
3. 3B = {3, 6, 9, 12, 15}
4. 4Numbers in both A and B: 6 and 12, so write 6 and 12 in the overlap
5. 5Numbers in A but not B: 2, 4, 8, 10, 14, so write these in A only
6. 6Numbers in B but not A: 3, 9, 15, so write these in B only
7. 7The numbers left over are 1, 5, 7, 11, 13, so write these outside both circles
8. 8Venn diagram complete: A only 2, 4, 8, 10, 14; overlap 6, 12; B only 3, 9, 15; outside 1, 5, 7, 11, 13

AnswerA only: 2, 4, 8, 10, 14; A ∩ B: 6, 12; B only: 3, 9, 15; outside both circles: 1, 5, 7, 11, 13
