Suppose that the load on an airplane wing is a random variable X obeying a normal probability law with mean 1000 and variance 14,400, whereas the load Y that the wing can withstand is a random variable obeying a normal probability law with mean 1260 and variance 2500. Assuming that X and Yare independent, find the probability that (that the load encountered by the wing is less than the load the wing can withstand).
