“在概率论中,如果除去一些可能构成一个零概率事件子集的样本点,其他的样本点都具有某种特性,那么我们就说这种特性是‘几乎必然’存在的。”
In more basic language, that essentially means that even when an event has a 100 percent chance of occurring, it won’t necessarily occur. For example, if you flipped a coin a million times, statistically, the odds of the coin landing on heads at least once is essentially one. However, there is an infinitesimally small chance that the coin could land on tails every single time. So although the odds of the event happening are for all intents and purposes guaranteed, it is impossible to say that.
更通俗地来说,上述定义本质上意味着即使一个事件发生的几率为百分之百,它也不一定就会发生。比如,你将一个硬币抛一百万次,从统计学上来说,硬币落下时至少有一次是正面朝上的概率基本上是1。然而,每次抛硬币时都存在极小的概率—硬币落下时是反面朝上的。因而即使确定一个事件发生的概率为百分之百,也不可能说它就一定会发生。

The word “the” is one of the most commons words in the English language. It’s so ubiquitous that most of us have probably never stopped to think about how strange of a word it actually is.
