So the expected value of a roll, let me do it here, expected value of a roll is going to be equal to 67.4 divided by 20. We can get our calculator out. Let's see, so we have 67.4 divided by 20 is 3.37. So this is equal to 3.37. So how does that help us? Well, we know how to calculate an expected value given this frequency table right over here. If we say that this number right over here, let's say that's capital A, and let's say that this number here is capital B.
