Hi, Initially X and Y are exponential random variables with rate respectively $$\mu \lambda$$, and I am aware that E[X|X>Y] is obtained using joint distribution but I(adsbygoogle = window.adsbygoogle || []).push({}); can not build up the integral structure, I intuitively think the result is just 1/mu, but I can not prove it to myselfcould you help me about that and building the integral structure??????
