[QUOTE="andrewkirk, post: 6047405, member: 265790"] The symbol ##\triangleq## means 'is defined to be'. Some people use := instead, or ##=_{def}##. The expression means the union, for all possible selections of k distinct integers in {1,...,m}, of the intersection of the k sets in ##A_1,...,A_m## that have those integers as index numbers. ##S## is the set containing the k chosen integers. It is not the sigma algebra. In other words: [LIST=1] [*]choose k of the sets ##A_1,...,A_m## and take their intersection. [*]Then take a different selection of k of those sets, take [I]their[/I] intersection, then combine that (take the union) with the set from the previous step. [*]Repeat that last step until all possible selections of k sets have been done. [/LIST] [/QUOTE]
