The joint probability density function of the quantity X of almonds and the

Y quantity of walnuts in a 1 lb can was

F(x,y)=(24xy.                0≤=x<=1,      0≤=y<=1,      x+y<=1      )

  1. otherwise


If 1 lb of almonds costs the company $ 1.50, 1 lb of walnuts costs $ 2.25 and 1 lb of peanuts cost $ .75, what will be the total cost of the contents of a can?, what will be the cost expected total?
