    Note sure if I need the ideas from sum of random variables
    A semi truck can transport a maximum of 14,950 pounds. Suppose that a load of cargo containing 115 boxes needs to be transported via this semi truck. Research has shown that the weights of boxes for this type of cargo have a relative frequency distribution that has a mean weight of 125 pounds and a standard deviation of 20 pounds. Based on this information, what is the probability that all 115 boxes can be safely loaded into the semi truck and transported? Interpret your answer in terms of a percentage and within the context of this problem.
