Discrete and continuous random variables - Khan Academy
Discrete random variables can only take on a finite number of values. For example, the outcome of rolling a die is a discrete random variable, as it can only land on one of six possible numbers. …
Random variables | Statistics and probability - Khan Academy
Random variables can be any outcomes from some chance process, like how many heads will occur in a series of 20 flips of a coin. We calculate probabilities of random variables and calculate expected …

A random variable is some outcome from a chance process, like how many heads will occur in a series of 20 flips, or how many seconds it took someone to read this sentence. Calculate probabilities and …

Random variables are really ways to map outcomes of random processes to numbers. So if you have a random process, like you're flipping a coin or you're rolling dice or you are measuring the rain that …

You have discrete, so finite meaning you can't have an infinite number of values for a discrete random variable. And then we have the continuous, which can take on an infinite number.
