Homework Statement
I am not sure if set theory is precalc or not but here is my question.
Find a pair set such that {a} belongs to the set and {a} is not a subset of S.
The Attempt at a Solution
So I thought that a set like this would work S = {{a}, b} because {a} belongs to the set, but in order for {a} to be a subset it has to be wrapped in more brackets so {{a}} is a subset. Am I right? If not what did I state that was wrong?
