In group 2, we had a total of 30 plus 110 is 140 people. And in the placebo group, the group that just got the sugar pill, we had a total of 120 people. And then we could also tabulate the total number of people that got sick. So that's 20 plus 30 is 50, plus 30 is 80. This is the total column right over here. And then the total people that didn't get sick over here is 100 plus 110 is 210, plus 90 is 300. And then the total people here are 380.
