You can either assign variable, you can assign values to them, or you can solve for them. You could say, hey, x is going to be 1 in this case. That's not going to be the case with a random variable. A random variable can take on many, many, many, many, many different values with different probabilities. And it makes much more sense to talk about the probability of a random variable equaling a value, or the probability that is less than or greater than something, or the probability that it has some property. And you see that in either of these cases. In the next video, we'll continue this discussion.
