answer with explanation

1. Consider a discrete time Markov chain with states 0, 1, ..., N whose matrix has elements j =i -1, di j = i+1, i, j = 0, 1, . .., N. Pij = 1 - di - Mi, j = i, 0. 1j - 2\\ > 1, Suppose that Mo = do = MN = AN = 0 and all other mi's and Mi's are positive, and that the initial state of the process is k. Determine the absorption probabilities at 0 and N
