# Rank of a random variable that follows a Uniform Distribution (0,1)

Well the question is a little easier .. Let X be a random variable that follows a Uniform distribution (0,1)(Uniform Standard). What is rank of the variable? (Values ​​can take). I have a confusion between whether the variable can take real values ​​between the interval (0,1) or can only take the values ​​0 or 1

 Can you write the density function for $X$ uniformly distributed over $[0,1]$? Those points with non-zero probability belong to the rank of $X$! – user21436 Jan 24 '12 at 17:00 @Kanna: Be careful that here, every point has zero probability... I see what you mean to ask by your second question but it needs to be slightly reformulated. – Did Jan 24 '12 at 17:08 @DidierPiau Thank You very much! Sure, I meant "non-zero density"! – user21436 Jan 24 '12 at 17:35 @Kan: Yes. With the further caveat that the density function is only defined almost surely... Hence for every point there exists a density function which is zero at this point... :-) – Did Jan 24 '12 at 17:47
