Hitting probabilities
Please help on hitting probabilities, I can't remember how to do this basic stuff.
Markov chain have states 14 has onestep transition matrix
$\displaystyle \left(\begin{array}{ccccc}\frac{1}{8}&\frac{1}{8}& \frac{1}{8}&\frac{1}{8}&\frac{1}{8}\\0&\frac{3}{4} &0&0&\frac{1}{4}\\0&0&\frac{1}{2}&0&0\\\frac{1}{2} &0&0&0&0\\0&\frac{1}{2}&0&0&\frac{1}{2}\end{array} \right)$
For each state $\displaystyle i$, find
$\displaystyle a_i = P$(process ever reaches K = {2,5}$\displaystyle  X_0 = i)$
Thank you

That is the probability of going from state two to state five. It is in row two and column five. Matrices are always listed (r, c) for row and column. The probability is one in four.

Thank you, just one more question.
So no matter how big the square matrix is, I just need to look at the row two and column five for that question?
