Probability of visiting state $s_1$ of a Markov chain more than $N$ times in $L$ steps.
Assume we have a two-state Markov chain, with $s_1$ and $s_0$ denoting the two states. The initial state of the Markov chain is either $s_1$ or $s_0$ with probability $p_1$ or $p_0$, respectively. The ...

random walk along edges of tetrahedron — which face gets hit last?
Suppose we have a tetrahedron $abcd$, and start at edge $ab$. Now walk to any "adjacent" edge (i.e. in this case any edge other than $cd$), each with equal probability $1/4$. This gives a stationary ...
