- A Troublesome Snowball One winter afternoon, unbeknownst to his mom, a child bring a snowball into the house, lays it on the floor, and then goes to watch T.V. Let W=W(t) be the volume of dirty water that has soaked into the carpet t minutes after the snowball was deposited on the floor. Explain in practical terms what the limiting value of W represents, and tell what has happened physically when this limiting value is reached.Find a value of k that will make f a probability density function on the indicated interval. ƒ(x) = kx; [2, 4]Find a value of k that will make f a probability density functionon the indicated interval.ƒ(x) = kx; [0, 3]
