Provide an appropriate response.A trailer rental company has rental and return facilities at both a north and south location in a city. Assume a trailer must be returned to one or the other of these locations. If a trailer is rented at the north location, the probability that it will be returned there is .6; if a trailer is rented at the south location, the probability it will be returned there is .65.
