Two drunks start out together at the origin, each having equal probability of making a step to the left or right along the x axi
s. find the probability that they meet again after n steps. it is to be understood that the drunks make their steps simultaneously. (it may be helpful to consider their relative motion.) (reif problem 1.8) hint: instead of considering that the two drunks make their steps simultaneously, consider the drunks making steps alternately.
