如果算出来是负的就是5%的概率损失超过u-1.65z，如果是正的就是95%的概率收益大于u-1.65z是么

NO.PZ2020033001000002 问题如下 Assuming thCompany A's profit anloss satisfy a normstribution, its annuaverage value is $30 million anits stanrviation is $10 million. Whiof the following statements about the calculation aninterpretation of the 95% Vvalue is correct? A.5% probability ththe company will lose least $13.5 million. B.5% probability ththe company will earn least $13.5 million. C.95% probability ththe company will lose least $13.5 million. 95% probability ththe company will earn least $13.5 million. is correct. 考点Parametric Estimation Approaches 解析95%的VaR=30-1.65*10=13.5m这道题的计算结果非常特殊，VaR值计算结果为正，无需取绝对值，也就是说有95%的概率盈利至少为13.5million。 那如果VAR是负就代表5%的概率损失超过数值，如果是正的就是95%的概率收益超过数值。应用到本题，不应该是5%的概率，损失超过13.55么？请问哪里理解不正确？

公式显示不正确 这个公式不应该用-U+ZV吗
