So the expected, so let me write it over here. I'll do expected in yellow. So the expected right over here, if you assume that 21% of each group should have gotten sick, is that you would have expected 25.3 people to get sick in group 1, in herb 1 group, and then the remainder will not get sick. So let's just subtract, or I could actually multiply 79% times 120. Either one of those will be good. But let me just take 120 minus 25.3, and then I get 94.7. So you would have expected 94.7 to not get sick.
