So we can say that Y can, its maximum value that it'll ever take on is five ounces, and the minimum value that it could ever take on, let's say it is three ounces. So given all of this information, what I wanna do is, let's just say I take a random box of mathies, and I take a random filled bowl, and I wanna think about the combined weight in the closed box and the filled bowl. So what I wanna think about is really X plus Y. I wanna think about the sum of the random variables. So in previous videos, we already know that the expected value of this is just going to be the sum of the expected values of each of the random variables. So it would be the expected value of X plus the expected value of Y, and so it would be 16 plus four ounces. In this case, this would be equal to 20 ounces. But what about the variation?
