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。
双语版 TED-Ed 演讲精选
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。
TED-Ed（视频版）
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.

中文百科
条件概率
本文定义了表征两个或者多个随机变量概率分布特点的术语。
条件概率（英语：conditional probability）就是事件A在另外一个事件B已经发生条件下的发生概率。条件概率表示为P（A|B），读作“在B条件下A的概率”。
联合概率表示两个事件共同发生的概率。A与B的联合概率表示为
或者
。
边缘概率是某个事件发生的概率。边缘概率是这样得到的：在联合概率中，把最终结果中不需要的那些事件合并成其事件的全概率而消失（对离散随机变量用求和得全概率，对连续随机变量用积分得全概率）。这称为边缘化（marginalization）。A的边缘概率表示为P（A），B的边缘概率表示为P（B）。
英语百科
Conditional probability 条件概率
In probability theory, conditional probability is a measure of the probability of an event given that (by assumption, presumption, assertion or evidence) another event has occurred. If the event of interest is A and the event B is known or assumed to have occurred, "the conditional probability of A given B", or "the probability of A under the condition B", is usually written as P(A|B), or sometimes PB(A). For example, the probability that any given person has a cough on any given day may be only 5%. But if we know or assume that the person has a cold, then they are much more likely to be coughing. The conditional probability of coughing given that you have a cold might be a much higher 75%.
