Let X and Y be continuous random variables that are uniformly distributed on the region defined by x20, y20, and x+4y≤20. In other words, there is a constant & such that the joint PDF is given by f(x,y)=k for points within this region, and the joint PDF is equal to 0 outside of this region. Find E[X] and E[Y].
