comment Suggestions for a real analysis reference.
I seem to remember Spivak (Calculus) having plenty of diagrams. If that's too low level, try Pugh's Real Mathematical Analysis. At some point the geometry is going to have to be behind the scenes, though... $\varepsilon$ and $\delta$ are the stars of the show in real analysis. I don't have any strictly topological suggestions, sorry.

comment Double Integration: $\iint_D\ e^{30x}\ dA$
i'd guess that the computer is interpreting (e^30 - 1) as (e^29)... try more parentheses? or (-1 + e^30)?

comment Prove the duality law for events
Is this using the notation that $AB = A \cap B$ and $A + B = A \cup B$? If so, draw a Venn diagram.

comment Getting the pmf from probability generating function?
1) use the product rule to find the derivative. 2) yes, there's an easier way, if you can recognize what distribution it fits (try some algebraic manipulation)
