Is the WeChat random lottery applet fair?

It is fair for WeChat to randomly extract applets.

It is fair to randomly select a small program on WeChat. It has gone through a lot of experiments, and then a small program like this comes out, so that people can have a way to decide things.

Randomness is a probability. If you are lucky, you may get you. If you are unlucky, there is no way to get your randomness. This is a relatively fair state.
