part c Let X be symmetric random walk in dimension with Xo = 0. This means that at each transition, the probability that the process moves unit to the right is as i8 the probability of moving one unit to the left: Wc have provcn in class that X has single communicating class which is recurrent This problem seeks to determine lintz-> P" for each Set up the infinite systein of equations to determine L possible, solve this system. Determine both and Xre, kfl , the expected return time to state
