Acivil engineering model for w, the weight (in units of 1000 pounds) that a span of a bridge can withstand without sustaining structural damage is normally distributed. suppose that for a certain span w∼n(400,402). suppose further that the weight of cars traveling on the bridge is a random variable with mean 3.5 and standard deviation 0.35. approximately how many cars would have to be on the bridge span simultaneously to have a probability of structural damage that exceeded 0.1?
