Suppose, because of random variations introduced during fabrication, the links of a chain have a random strength, whereby the failure load is a normally distributed (i.e., Gaussian) random variable with a mean of 10,000 lbs and a standard deviation of 300 lbs. The load to be applied to the chain is 9,000 lbs. Plot the reliability of the chain vs. the number of links comprising the chain, with the number of links varying from 1 to 1000.
