My random variable $y$ belongs to a finite set of real numbers. I am writing a document and I need to write something like $y\in \mathbb{R}$. what should I put next to $\mathbb{R}$ which shows that its a finite set?

    What do you mean by that the random variable "belongs to a finite set of real numbers"? Do you mean that there are only finitely many values that the random variable takes on with nonzero probability? – qaphla Jun 26 '15 at 22:50

    There is no "correct notation". But this was discussed several times before. This is probably a good start. – Asaf Karagila Jun 26 '15 at 22:51

    You could say something like $y\in {y_1,...,y_n}\subseteq\mathbb R$. – Plutoro Jun 26 '15 at 22:54
  • @ qaphla . … thats exactly what I mean. e.g $y\in[1.5,0.5,0.-0.5]$. This set has finite number of entries and each entry belongs to $\mathbb{R}$ – NAASI Jun 26 '15 at 22:55
  • Use curly braces (with latex, by using \{ and \}) around your finite set of numbers, and that's exactly what you can write. – pjs36 Jun 26 '15 at 22:57
  • Thanks guys….atleast now I know that I am not missing something here. This leaves a room for us to be creative :) – NAASI Jun 26 '15 at 22:57
