rephrase the following: Yes. Connors is contributorily negligent for its failure to take safety precautions by having an employee aboard the barge during the daylight hours. Liability for negligence due to failure to take safety precautions exists if the burden of taking such precautions is less than the probability of injury multiplied by the gravity of any resulting injury. This formula may be symbolized mathematically by B < PL = negligence liability, where "B" is the burden of adequate precautions, "P" is the probability of injury, and "L" is the injury itself. The burden of taking precautions for Connors was nothing more than paying its employee to remain on the barge during normal working hours, when the incident occurred. If he had been on board, he could have called for help from the tug boats when the barge broke free and possibly avoided the damage. The likelihood of a barge breaking free is relatively high, especially in instances of severe weather. This likelihood is increased when the employee tasked with manning the barge is absent. The potential injury resulting from a barge breaking free is quite significant and may, as with the Anna C, result in total loss of the barge. Thus, compared with the relatively high risk of injury multiplied by the gravity of the injury, the burden on Connors to take precautions is relatively low. Connors is thus contributorily negligent for its failure to take safety precautions by having an employee aboard the barge during the da
