This problem is an example of conditional probability.

这个问题是条件概率的一个例子。

This is how conditional probability works.

这就是条件概率。

And conditional probability isn't just the stuff of abstract mathematical games.

条件可能性并不只是抽象的数学游戏。

If you're wondering how this could possibly be right, it's because of something called conditional probability.

如果你在想这怎么可能是正确答案，是因为条件可能性。

This is known as the conditional, or posterior probability, determined once the possibilities have been narrowed down through observation.

这被称为条件概率或后验概率，一旦通过观察缩小了可能性就足以确定了。

Computers and other devices use conditional probability to detect likely errors in the strings of 1's and 0's that all our data consists of.

电脑和其他的装置会使用条件可能性在1 和 0 中 来侦测我们数据中的潜在错误。

“The Cartoon Guide to Statistics” promised readers they would chew over binomial distributions and conditional probability with the same ease with which they enjoyed Spider-Man.

那年一本名叫《统计学卡通指南》的书，承诺可以让读者津津有味地学习二项分布和条件概率，就像阅读《蜘蛛侠》一样轻松愉快。

Conditional Probability: The probability of an event given that another event has already occurred.

条件概率：给定另一个事件已经发生的事件的概率。
