Let me pick a new color. The variance is just, you could view it as the probability weighted sum of the squared distances from the mean or the expected value of the squared distances from the mean. So what's that going to be? Well, there's two different values that anything can take on. You can either have a 0 or you could either have a 1. The probability that you get a 0 is 0.4. So there's a 0.4 probability that you get a 0.
