The difference between 1 and 0.6, 1 and our mean, 0.6, is that, and then we are also going to square this over here. Now what is this value going to be? This is going to be 0.4 times 0.6 squared. This is 0.4 times 0. Because 0 minus 0.6 is negative 0.6. If you square it, you get positive 0.36. So this value right here, I'm going to color code it, this value right here is times 0.36.
