The variance expectation is clear, and the density function is at your fingertips!
There is no need to look up the table if the mind is in a normal state, the discreteness and continuity are all under control!
The index is automatically integrated when the head is raised, and Poisson is wiped out in ashes while talking and laughing!
The place he wants to go is full of bones, and the place he walks through is full of flowers!
If there is no torch from now on, I will be the only light!
