$1,682 $998,318 $498,318 ANSWER: in the previous question, the monthly fault probability is 0.00168. The following table shows the stribution of cret losses. This gives expecteloss of $1,682, the same before. Next, $500,000 is the Wa minimum 99.9% confinlevel because the totprobability of observing a number equto or lower ththis is greater th99.9%. The cret Vis then $500,000 - $1,682 = $498,318. 为什么WCL是500,000.00？
