So you would have expected 94.7 to not get sick. So this is expected again. 94.7 to not get sick. 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.
