A rope is manufactured with breaking strength that is distributed (approx.) normal with mean 500 Ibs, and standard deviation 25 Ibs. The users of these ropes subject the rope to a load that is distributed (approx.) normal with mean 420 Ibs, and standard deviation 30 lbs. If the rope strength and load are independent random variables, find the probability that any one instance of using these ropes under these loading conditions will break.
