Answer 1

I'll describe the 3‑circle Venn diagram regions for sets L, M, N and give the union and intersections.

Regions (three overlapping circles labeled L, M, N):

- L ∩ M ∩ N (center, all three): {A, B}
- L ∩ M only (in L and M but not N): {C, cow}
- L ∩ N only (in L and N but not M): {duck}
- M ∩ N only (in M and N but not L): {3}
- L only (in L but not in M or N): {Y, −1, Δ}
- M only (in M but not in L or N): {2, pig}
- N only (in N but not in L or M): {0, 1, horse}

Union and intersections:
- L ∪ M ∪ N = {A, B, C, Y, −1, cow, duck, Δ, 2, 3, pig, 0, 1, horse}
- L ∩ M ∩ N = {A, B}
- Pairwise intersections:
- L ∩ M = {A, B, C, cow}
- L ∩ N = {A, B, duck}
- M ∩ N = {A, B, 3}

If you want, I can draw a simple ASCII Venn diagram with these region labels.
