Hi everybody, Given is the following joint distribution of the 2-dimensional random variable (X1,X2). f(x1,x2)=(1/(2*x1); if 0<x2<x1 ;0<x1<2; 0; otherwise How do I get the two marginal pdf f(x1) and f(x2)? Thanks for your help!

Thanks for your help! It helps if you sketch the region over which the density is non-zero: CB
