We introduce auxillary random variable W=Y

Now we have Z=X/Y and W=Y i.e. z=x/y and w=y

∴x=zy=zw and y=w ∴J=

∴J==y We know the joint probability density function $f_{ZW}$ (z,w)=|J| $f_{XY}$ (x,y)=|y|$f_{XY}$ (x,y)

Since X and Y are independent random variables

$f_{XY}$ (x,y)=$f_X$ (x).$f_Y$ (y)

Since X and Y …
