So I encourage you to pause this video and think about it on your own before I give a go at it. So first, let's think about what this expected value, the sum of 20 rolls, being 67.4 tells us. That means that the expected value of one roll, the expected value of the sum of 20 rolls is just 20 times the expected value of one roll. 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.
