Consider a random walk on {0, 1, . . . , N } with jump probabilities p(x,x+1)=1/3, p(x,x−1)=2/3 for1≤x≤N−1 p(0,0)=1−c, p(0,1)=c, p(N,N)=1−c, p(N,N−1)=c with p(x, y) = 0 for all other cases. (Here c is a fixed number in (0, 1).) Find the expected return time to 0 if we start the process there.
please answer it asap due in 10 hours. thanks

4. (Dobrow 2.5) Consider a random walk on {0,...,k}, which moves
left and right with respective probabilities q and p. If the walk
is at 0 it transitions to 1 on the next step. If the walk is at k
it transitions to k−1 on the next step. This is called random walk
with reflecting boundaries. Assume that k = 3, q = 1/4, p = 3/4, and
the initial distribution is uniform.

Problem 1: Random Walk A random walk is a stochastic process. A stochastic process is a series of values that are not determined functionally, but probabilistically. The random walk is supposed to describe an inebriated person who, starting from the bar, intends to walk home, but because of intoxication instead randomly takes single steps either forward or backward, left or right. The person has no memory of any steps taken, so theoretically, the person shouldn't move...
