Or I could even say 0.6 minus 0. Same thing because we're going to square it. 0 minus 0.6 squared. Remember, the variance is the probability or the weighted sum of the squared distances. So this is the difference between 0 and the mean. And then plus, there's a 0.6 chance that you get a 1. 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.
