Definition of Discrete Uniform Distribution

A discrete random variable $X$ is said to have uniform distribution with parameter $a$ and $b$ if its probability mass function is given by

$$f(x; a,b) = \frac{1}{b-a+1}; x=a,a+1,a+2, \cdots, b $$

Distribution function of Uniform Distribution

$$P(X\leq x) = F(x) = \frac{x-a+1}{b-a+1}; a\leq x\leq b $$
