Asked by Adam
                1. The random variables  X  and  Y  are distributed according to the joint PDF
fX,Y(x,y) = {ax2,0,if 1≤x≤2 and 0≤y≤x,otherwise.
 
Find the constant a.
2. Determine the marginal PDF fY(y) .
(Your answer can be either numerical or an algebraic function of y ).
a. If 0≤y≤1 :
fY(y)=
  
b. If 1<y≤2 :
fY(y)=
