"WebThis is true even with arbitrary unions. Furthermore, the union of a finite number of closed sets is closed, and we have Bn ⊂ ∪ni = 1¯ Ai, so it follows that ¯ Bn ⊂ ∪ni = 1¯ Ai. This is not necessarily true with infinite unions. Another example illustrating the latter point is Ai = 1 i = ¯ Ai, then 0 ∈ ¯ B ∖ ∪∞i = 1¯ Ai. Share Cite " - Sets union subset
