And now let's do that for each of these groups. So once again, group 2, you would have expected 21% to get sick, 21% of the total people in that group, so that's 140. So that's 29.4. And then the remainder, 140 minus 29.4, should not have gotten sick. So that gets us this right here. We have 20, 29.4 should have gotten sick if the herbs did nothing. And then over here, we would have 110.6 should not have gotten sick.
