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. It is equal to 2.1. And if I wanted to figure out the standard deviation of this right over here, I would just take the square root of this. So if you want the standard deviation, just take the square root of this expression right over here.
