6. Suppose that the sunken barge in United States v. Carroll Towing Co. and its cargo are worth $100000. Assume that the probability of the barge breaking loose it the bargee is not present equals 0.001. The expected cost of an accident In the absence of a bargee is if the bargee Is present. then the probability of the barge breaking loose is reduced by half to 0.0005. Then, the expected cost of an accident In the presence of the bargee is The expected reductiong in the cost of an accident due to the bargee's presence is If paying the bargee to stay on the barge costs the barge owner $25, the Hand rule dictates that the barge owner is (negligentot negligent) if no bargee is present during the mooring readjustment
