Problem 32E Fire load (MJ/m2)is the heat energy that could be released per square meter of floor area by combustion of contents and the structure itself. The article Fire Loads in Office Buildings (J. of Structural Engr., 1997: 365368) gave the following cumulative percentages (read from a graph) f

A motorist goes through 4 lights, each of which is found to be red with probability 1/2 . The waiting times at each light are modeled as independent normal random variables with mean 1 minute and standard deviation 1/2 minute. Let X be the total waiting time at the red lights. (a) Use the total proba
