问一道题：NO.PZ2020010301000003 [ FRM I ]

  1. FRM I
  2. Quantitative

问题如下：

What are the sample spaces, events, and event spaces if you are interested in measuring the probability of a corporate takeover and whether it was hostile or friendly?

解释：

Using the notation No Takeover (NT), Hostile Takeover (HT) and Friendly Takeover (FT), the sample space is {NT, HT, HT}. The events are all distinct combinations of the sample space including the empty set, ø, NT, HT, FT, {NT, HT}, {NT, FT}, {HT, FT}, {NT, HT, FT}. The event space is the set of all events.

答案中后面的集合是什么意思 可能发生的情况不就是未并购 友善并购 恶意并购三种吗？

同学你好，这题单纯考的是这几个概念：

样本空间就是样本事件的可能情况，也就是那三个，NT，HT和FT。事件是这三个事件再加上空集的任意组合。事件空间是所有事件构成的集合。

这道原版书的题出的有点偏了，太偏概率论原理的范畴了

那这道题的事件空间是什么

品职答疑小助手雍 · 2020年03月08日

事件空间就是 ø, NT, HT, FT, {NT, HT}, {NT, FT}, {HT, FT}, {NT, HT, FT}这些所有的组合。

The event spais the set of all events. 根本不可能发生的事件，为什么也算到event space里面呢？意义何在？比如{NT,HT}、{NT,FT}、{NT、HT、FT}
