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. If we were to try to calculate the expected value of a roll, what we really want to do is take the weighted frequency of each of these values, the weighted sum. So for example, if we got a one A out of 500 times, it would be A out of 500 times one, plus, I'll do these in different colors, plus 110 out of 500 times two, plus 110 out of 500 times two. Notice, this is the frequency, which was they got two, times two, we're taking a weighted sum of these values.
