Solved: In Exercise 5.12, we were given the following joint probability density function
Chapter 5, Problem 5.107(choose chapter or problem)
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. For the two chemicals under consideration, an important quantity is the total proportion Y1 +Y2 found in any sample. Find E(Y1 + Y2) and V(Y1 + Y2).
