Can someone help me with this problem. Any help or insight would be appreciated thank you.

(3) Let X, be a Bernoulli(p) process indexed by n E Z. Imagine we stand half-way between n = 0 and n = 1. We look both to the left and to the right for a successful trial. We count in both directions up to and including the first success; let Z denote the total. Find the law of Z and compute its mean. Compare the mean of Z with the mean waiting time for this process.
