Question: Show that R(1)=1

Consider generalizing in the following way: N customers line up for their sandwiches, and you are the last customer
in line; the first customer grabs a sandwich at random, and every customer afterwards attempts to take their own
sandwich, or will grab one at random. Define R(N) to be the probability that you get your own sandwich in this
situation.
