And then if we total the number of people who had a longer right foot, 11 plus two plus 12, that's 13 plus 12, that is 25. Longer left foot, three plus nine plus 13, that's also 25. And then we could either add these up and we would get 50 or we could say, hey, 25 plus 25 plus what is 100? Well, that is going to be equal to 50. Now, to figure out these expected values, remember, we're going to figure out the expected values assuming that the null hypothesis is true, assuming that these distributions are independent, that feet length and hand length are independent variables. Well, if they are independent, which we are assuming, then our best estimate is that 22% have a longer right hand and our best estimate is that 25% have a longer right foot. And so out of 100, you would expect 0.22 times 0.25 times 100 to have a longer right hand and foot.
