老师你好,在计算IS中的interest cost和interest income的时候,使用的利率,之前看到的是即期市场利率,这次洪老师讲的是折现率,折现率用的是相同久期high quality coporrate bond的利率,请帮忙确认下到底应该是哪一个?
已回答There are two funds: A and B. P(A gain | B gain) = 0.4, P(B gain | A gain) = 0.35, P(A gain and B gain) = 0.14. The probability of at least one of the two funds gain is closest to: A 0.46 B 0.59 C 0.61 查看解析 上一题 下一题 正确答案C 您的答案C本题平均正确率:82% Calculation rules for probabilities难度:容易 推荐: 答案解析 P(A)=P(AB) / P(B | A) = 0.14 / 0.35 = 0.40, P(B)=P(AB) / P(A | B) = 0.14 / 0.4 = 0.35, P(A or B)=P(A)+P(B)-P(AB)=0.40+0.35-0.14=0.61. 请问:我直接用P(B | A)+P(A | B)-P(AB)也是0.61,是巧合吗?
查看试题 已回答The probability of Event A is 40%. The probability of Event B is 60%. The joint probability of AB is 40%. The probability (P) that A or B occurs, or both occur, is closest to: A 60% B 84% C 40% 查看解析 上一题 下一题 正确答案A 您的答案B本题平均正确率:78% Calculation rules for probabilities难度:容易 推荐: 答案解析 P(A or B) = P(A) + P(B) – P(AB) = 0.40 + 0.60 – 0.40 = 0.60 or 60%. 请问:这里没说A,B是什么关系,即独立?互斥?感觉直接用文氏图来求解有点不严谨?
