And to figure that out, we just have to figure out how many standard deviations above the mean we are, which is going to be our z-score. And then we could use a z-table to figure out what this area right over here is. So we want to know, when we are above 2.2 liters, so 2.2 liters, we could even do it in our head, 2.2 liters is what we care about. That's right over here. That is, our mean is 2, so we are 0.2 above the mean. And if we want that in terms of standard deviations, we just divide this by the standard deviation of this distribution over here. And we figured out what that is.
