comment How can we directly see that the number of random walks starting and ending at the origin is ${n\choose n/2}^2$?
@IanMateus I've changed it quite a bit, I think the problem in my last one was that I forgot to consider the walks that were made of say more NS than EW.

Well if there is only $1$, everybody will always have the same output, so you won't be able to determine the leader.

$L$ should also be greater than $1$ I guess

$\sin(x)/x$ converges to $1$ as $x$ goes to $0$.

I'm also confused, since the example given is wrong. Also, you have a typo, $t_n/s_n$ converges to $t/s$, provided $s\neq 0$.
