Find the elements in A intersection B intersection C
Answer by CPhill(1959) (Show Source):
You can put this solution on YOUR website! The intersection of sets A, B, and C (A ∩ B ∩ C) contains only the elements that are present in *all three* sets.
* **A = {z, y, x, w, v, u}**
* **B = {x, w, v, t, s, r}**
* **C = {u, v, p, q, r}**
Looking for common elements:
* 'v' is present in all three sets.
* No other elements are shared by all three sets.
Therefore, A ∩ B ∩ C = {v}
