$X,Y$ are independent exponential RV with parameter $\lambda,\mu$. How to calculate

$$ E[\min(X,Y) \mid X>Y+c] $$

    Do you intend the parameters to be the _rates_, so that the density is $\lambda e^{-\lambda x}$ on $(0,\infty)$, or the expectations, so that the density is $(1/\lambda)e^{-x/\lambda}$ on $(0,\infty)$? Both conventions are sometimes used.2012-12-18

    In TeX you should write \min, not \text{min}. Then something like f\min g has proper spacing before and after $\min$, thus $f\min g$. Also, when in a "displayed" rather than "inline" setting, something like \min_{x\in A} looks like this: $\displaystyle\min_{x\in A}$.2012-12-18

    @MichaelHardy, the parameters is the rates and thank you for advise in latex~2012-12-19
