comment probability problem explanation
+1, and thanks for the head's up on my answer. Looks like I misread the OP due to typos. Will probably remove my answer so as not to cause confusion.

comment How to get the numbers that multiplied with $N$ become integers?
Minor nit: Include the assumption $GCF(p,q)=1$, i.e. the fraction ${p}\over{q}$ is in reduced form to ensure $q | N$.

comment Is this question too easy or am I getting it wrong?
I know. I was referring to the phrasing of the title question, "Is this question too easy...". This question is very easy, but from a teaching perspective the objective of such a question is not to be a difficult limit problem, but to catch students using such techniques inappropriately.

comment Is this question too easy or am I getting it wrong?
You seemed surprised at how easy this one was, but the point of problems like this is to impress upon students that techniques for resolving undefined or indeterminate values (like L'hôpital's Rule) can give you the wrong answer if applied in this context.

comment Data Analysis & Probability
Sorry, I can't get into chat right now (firewalled) but I'm really curious about the reasoning behind the numbers in your equation. If you can explain where you got those, it might illuminate specific misconceptions that we could help you correct...

@user115595 Sorry, misread your comment. We're saying the same thing. ;-)

comment Spivak's “Calculus in Manifolds” problems
Actually, the text seems to ask you to prove that $\partial A$ has measure $>0$, which seemed like the correct question given we're proposing a version of $A$ that cannot logically cover the full measure of $[0,1]$, since that summation implies the measure of $A<1$...

I don't speak Spanish, but doesn't 3.11 say prove that the border of A does not have measure $0$?
