WebStatistics and Probability questions and answers. 1. Generalize DeMorgan's Laws to arbitrary unions: Let A be a collection of sets, let U be a set, and assume A C U for every A EA. You may use the notation A" = U\A for the complement of A in U and supress the "universal set" U in your proofs so you don't have to keep repeating "x EU." おやつタウン 大阪 閉店

Webassume de Morgan's law holds for an index set of size n Then prove that it holds for an index set of size n + 1 and wrap it up by n → ∞ but I'm not convinced that's right. For example, an argument like that doesn't work for countable intersection being closed on a collection of open sets.
