We should get 79% as well. So one would expect that 21% of each of your total, based on the total sample right over here, our best guess is that 21% should be getting sick and 79% should not be getting sick. So let's look at it for each of these groups. If we assume that 21% of these 120 people should have gotten sick, what would have been the expected value right over here? So let's just multiply this 21% times 120. That gets us to 25.3 people should have gotten sick. So the expected, so let me write it over here.
