The sample space is {Default, No Default}. Events are subsets of a sample space. In the corporate default example, the event space is{Default, No Default, {Default, No Default}, }. It might appear surprising that the event space contains two "impossible" events for this example:1. {Default, No Default}, which contains both outcomes; and2. The empty set , which contains neither.

同学,你好,这是对于样本空间的定义,在这里是所有可能情况的组合,即违约、不违约,违约和不违约同时发生、违约和不违约都不发生,虽然后面两种情况不会在现实生活中出现,但是也算一种事件。
