Chapter 3.4, Problem 8MS

The power of sets (S). Let $\text{S =}\left\{\text{!,@,\#, \$, \%, \&}\right\}\text{.}$

Below are two columns: on the left are names of certain sets, and on the right are confusing-looking thingies—each thingie is an element of one of the sets in the left-hand column. Your mission, if your instructor chooses to assign it, is as follows: For each thingie in the right-hand column, determine which set from the left-hand column contains that thingie as a member. As examples, we have done the first two for you: $\left\{\text{!, @}\right\}$ is a subset of S, so it is an element of the power set (S), and @ is a member of S itself. Okay, now you’re on your own! Good luck.
