5,806 PointsQuestion about status of _random changed
At 4:50, when you say the status of _random changed when we want to get a random number, I am a bit confused, since it is a static field in a static class, why _random is not immutable?

What "static" does is to allocate space for it associated with the class itself, so an instance doesn't need to be created.
