Thanks, can you elaborate a bit more, or tell me where to look for?

comment Pen, pencils and paper to write math
Recently I've had a similar experience in a train. I use a plastic card for travelling, so no tickets unfortunately, so I've used a train company booklet

comment If a measure $\mu$ is less than a measure $\nu$ on a generating $\pi$-system, can we conclude that $\mu \leq \nu$?
@echinodermata: since set of measure on $n$ points is exactly $\Bbb R^n$, I just use this notation to say that $\mu(a)=1$, $\mu(b)=0$, and similarly $\nu(a)=0$, $\nu(b)=1$

@EvanAad: edited. The first condition does not seem to be relevant here at all, it's purely measure theoretical question, you can add to my $\Omega$ the interior without changing anything. The second condition might have been important, but apparently no: a simple edit of my original example took care of that.

As you said, you already know the PDF for $S_n$.

Indicator is a function of the form $1(x\in A)$, but it seems you only have $1(x)$ which is missing some important information.

For the first one, I think $K \geq n \iff S_n \leq T$.
