Problem 3 [20 points) The anchorage system of a suspension bridge consists of ll cable strands. The strength of each cable strand is modeled as a random variable with mean value 100 kips and a coefficient of variation of 18%. Cable strand strengths are independent of each other. The overall load acting on the anchorage systems is modeled as a Gaussian random variable with mean value 5.11% kips and a coefcient of variation of 12%. What is the probability of failure of this anchorage system
