discrete uniform distribution
lower bound parameter
upper bound parameter
The discrete uniform distribution is a discrete probability distribution with probability function given by:
subject to the following conditions:
Note that the DiscreteUniform command is inert and should be used in combination with the RandomVariable command.
X ≔ RandomVariable⁡DiscreteUniform⁡a,b:
The variance of X is a somewhat messy expression, because of all the ceil and floor functions.
If we know that a and b are integers, we can apply these assumptions to make the expression easier to read.
