For the last time, there is no secret exit from the bathroom!
我在最后重申一遍：“浴室里面没有秘密出口！”
For the last time, there is not a secret exit from the bathroom.
最后一次声明，卫生间里没有啥秘密的出口。
In the former two situations, the exit time is assumed to be a random variable and in the last situation the exit time is assumed to be a stochastic process.
对前两种情形考虑退出时间是个随机变量，对最后一种情形考虑退出时间是个随机过程。
