Does my edit (with solution) look like what you're saying or is this not right? Dec 31 revised Calculating probability in a Markov Chain added 303 characters in body Dec 30 comment Calculating probability in a Markov Chain +1 that makes sense to my data. I had very little stochastics training, and am trying to understand $\pi_A=\pi_AP_{AA}+\pi_BP_{BA}$. I see the $P_{AA}$ and $P_{BA}$ but I'm not sure where you're getting $\pi_A$ and $\pi_B$ from, since it's on both the right and left sides of the equation. I took a beginning stochastics class a long time ago, but didn't go anywhere near this depth, nothing about Markov Chains, so I'm teaching it to myself now.

So, yes the ratio. The percent probability for each in $\{A,B\}$ Dec 30 asked Calculating probability in a Markov Chain Dec 9 accepted Consider this grammar Dec 8 accepted Grammar outside the Chomsky Hierarchy Dec 8 comment Grammar outside the Chomsky Hierarchy Yes the $\lambda$ would be the empty string, and so that's a production starting from nothing to something.
