Well, now when I calculate the sample mean, the average of one and three or the mean of one and three is going to be equal to two. Let's think about all of the different scenarios of samples we can get and what the associated sample means are going to be. And then we can get see the frequency of getting those sample means. And so let me draw a little bit of a table here. So make a table right over here. And let's see, these are the numbers that we pick. And remember, when we pick one ball, we'll record that number, then we'll put it back in and then we'll pick another ball.
