我记着还有一个soft hurdle rate,和hard hurdle rate 怎么区分

B选项是early stage的特征哇？

为什么B比C更可能？这种可能性怎么比较的

这道题B选项我理解的意思是：雇主每期向员工退休账户contribute贡献，这样理解就符合DC plan呀，和你讲的完全不同。我没明白有什么错。能详细讲解下B选项的意思吗？我觉得我理解的意思没有错。

老师您好，在做这道题之前做了一道需要在计算机上输入10个X的的题目，而这道题只有5个X的输入。如何清空前一题的10个X。因为即使我重新输入这个5个X, 按ENTER, X6到X10显示0， 出来的STAT 不对。

Asume that a stock's price over the next two periods is as shown below. The initial value of the stock is $200. The probability of an up move in any given period is 30%, and the probability of a down move in any given period is 70%. Using the binomial model, the probability that the stock's price will be $201.20 at the end of two periods is closest to 老师，这个题怎么和二项式联系，麻烦再讲讲

If two events, A and B, are independent and the probability of A does not equal the probability of B [i.e., P(A) ≠ P(B)], then the probability of Event A given that Event B has occurred [i.e., P(A│B)] is best described as: A P(A). B P(B│A). C P(B). 老师这个题麻烦讲解下，

参考老师课上讲的，是自己国家剔除自己国家的物件水平，难道不是应该（（1 8.5%）/(1-5%) ）/（1/(1 3.5%)）-1吗？ 为什么剔除物价水平影响，分子处是*（1-5%），而分母是除？

这个，远期合约不想交易了不是买一个相反的合约就好了么，之前看涨合约想退出就买个看跌的。这个不行么

A company has an unsecured line of credit and needs to maintain its EBIT-to-interest coverage ratio greater than 2.0. Its EBIT is estimated to be between $36 million and $48 million, with all values equally likely. If the forecasted interest charge for the year is $20 million, the probability that EBIT/interest will be more than 2.0 is closest to: A 66.7%. B 61.5%. C 33.3%. 这个题读不懂，需要讲解下
