That comes straight from the meaning of the word discrete in the English language. Distinct or separate values. While continuous, and I guess there's another definition for the word discrete in the English language, which would be polite or not obnoxious or kind of subtle, that is not what we're talking about. We are not talking about random variables that are polite. We're talking about ones that can take on distinct values. And continuous random variables, they can take on any value in a range. And that range could even be infinite.
