You can see that the dash distribution I drew has more out in the tails, so we call it fat-tailed.
你们可以看到,虚线画的这个分布,尾部要长很多,所以我们叫它长尾分布

You might say the probability that you toss a coin and it comes up heads is a half, because it's equally likely to be heads and tails.

For example, the experiment could be tossing a coin, I will call the outcome heads the number one, and I'll call the outcome tails the number zero, so I've just defined a random variable.
比方说,抛硬币的试验,我将正面向上的结果对应数字1,反面向上的结果对应数字0,这样我就定义了一个随机变量
