Quick Set Question
 
If a set "C" can contain any subset of a set "A", then is "A" itself a subset of (or equal to) "C" ??

:blushing:

Do you mean by "contain" "has as a subset"? If that is the case, then the answer is "yes". If C has every (proper) subset of A as a subset, then, in particular, it has every singleton set as a subset and so contains every element of A.

Thanks -- just what I needed to know :smile:
