So there we go. We deserve a little bit of a drum roll. The variance of x is equal to n times p times one minus p. So if we were to take the concrete example of the last video, where if I were to take 10 free throws, so each trial is a shot, is a free throw. So if I were to take 10 free throws and my probability of success is 0.3, I have a 30% free throw percentage, the variance that I would expect to see, so in that case, the variance, if x is the number of free throws I make after these 10 shots, my variance will be 10 times 0.3, 0.3 times one minus 0.3, so 0.7. And so that would be what? This right over here, so this would be equal to 10 times 0.3 times 0.7 times 0.21. So my variance in this situation is going to be equal to 2.1.
