So three out of the nine possibilities, we got a two. So we could say this is two, or we could say this is 3 9th, which is the same thing, of course, as 1 3rd. So this right over here is three over nine. And then what about 2.5? Well, there's two 2.5s, so two out of the nine times. Another way you could interpret this is, when you take a random sample with replacement of two balls, you have a 2 9th chance of having a sample mean of 2.5. And then last but not least, right over here, there's one scenario out of the nine where you get 2 3, so 1 9th.
