问题如下：
Which of the following best describes how an analyst would estimate the expected value of a firm under the scenarios of bankruptcy and survivorship? The analyst would use:
选项：
A. the addition rule.
B. conditional expected values.
C. the total probability rule for expected value.
解释：
C is correct.
The total probability rule for expected value is used to estimate an expected value based on mutually exclusive and exhaustive scenarios.
请问全概率公式在讲义的哪里呀 谢谢NO.PZ2017092702000066问题如下Whiof the following best scribes how analyst woulestimate the expectevalue of a firm unr the scenarios of bankruptansurvivorship? The analyst wouluse:A.the aition rule. B.contionexpectevalues. C.the totprobability rule for expectevalue. C is correct.The totprobability rule for expectevalue is useto estimate expectevalue baseon mutually exclusive anexhaustive scenarios.本题涉及如果未来只有破产和不破产这两种情况下，如何计算公司的expectevalue。那么全概率公式来解决就即可。 请分别下a和为啥错

NO.PZ2017092702000066 我记得有道题是根据下一年市场好/坏/均衡，来算预期的点位。用的就是加法法则。这道题是预期的破产/继续运行，两种概率，为什么就不能用加法法则了呢老师？
没读懂题目跟答案…可以翻译讲解一下吗
