Problem 5.56

In Exercise 5.12, we were given the following joint probability density function for the random variables Y1 and Y2, which were the proportions of two components in a sample from a mixture of insecticide: f (y1, y2) = 2, 0 y1 1, 0 y2 1, 0 y1 + y2 1, 0, elsewhere. Are Y1 and Y2 independent?
