In this lesson, we are going to talk about random variables. The idea that goes along with that is the probability distribution, and we are going to learn what those terms mean. We will start with the intuition for random variables and try to give you an idea of roughly what they mean. After that, we'll see the formal definition. We will also define the probability distribution, which can be a little confusing at first, but it will make more sense after we do some examples. You'll see how the probability distribution is the sum of all the probabilities of the outcomes for which Y=y.
