A manufacturing plant produces cylindrical metal rods. The diameter, $D$, of a rod is a random variable, as is the length, $L$, of the rod. $D$ is a continuous random variable, while $L$ is a discrete random variable.
Explain how the nature of the manufacturing process might lead to $D$ being modeled as a continuous random variable and $L$ as a discrete random variable. Furthermore, explain why, in reality, both variables could be considered discrete.
