say we have integers 0-10. We start with N and the probability that N grows by 1 is .69. The probability that N decreases by 1 is .31. Thus obtaining N+1 after one time step is .69 and similar obtaining N-1 is .31. Once N reaches 0 or 10 it is absorbed and cant move from there. My question is what is the probability that N is eventually at 10 if we start at N=2? also what is the probability of absorption if we start at N=2?
