And then they also give us the mean of X and the standard deviation of X. Then they tell us if the game costs Anoush $15 to play and he wins $10 per shot he makes, what are the mean and standard deviation of his net gain from playing the game N? All right, so let's define a new random variable N, which is equal to his net gain, net gain. We can define N in terms of X. What is his net gain going to be? Well, let's see, N, it's going to be equal to 10 times however many shots he makes. So it's gonna be 10 times X.
