WebOct 2, 2024 · By definition, a discrete random variable contains a set of data where values are distinct and separate (i.e., countable). In contrast, a continuous random variable can take on any value within a finite or infinite interval. Thankfully the same properties we saw with discrete random variables can be applied to continuous random variables.
