问题如下:
If a Portfolio's SFR is 1.4 and threshold level's return is supposed to be 2%, what is the probability of return less than 2%?[F(1.4)=0.9192]
选项:
A.
8.08%.
B.
30.20%.
C.
9.68%.
解释:
A is correct.
Using the table, we get F( -1.4) is 1 - 0.9192 = 8.08%.
这题是否一定需要查表吗? 因為用1 減去題目0.9192 也是剛好0.0808,这种方法是巧合吗?
