So this all boils down to what is the variance of y going to be equal to? So let me scroll over a little bit, get a little bit of more real estate, and I will figure that out right over, right over here. All right, so we want to figure out the variance of y. So variance of y is going to be equal to what? Well here it's going to be the probability squared distances from the expected value. So we have a probability of p, where what is going to be our squared distance from the expected value? Well, we're gonna get a one with a probability of p. So in that case, our distance from the mean, or from the expected value, we're at one.
