$\displaystyle f(x,y)=\frac{2}{x^2(x-1)}y^{-(\frac{2x-1}{x-1})}$ for x > 1, y > 1

Given that the initial claim estimated by the company is 3, determine the probability that the final settlement amount is between 2 and 4 .

$\displaystyle \int_1^{\infty}\int_1^{\infty}\frac{2}{x^2(x-1)}\int_1^{\infty}y^{-(\frac{2x-1}{x-1})}dy$

thank you for your help. thank you a lot
