If $U$ is a Uniform(0,1) random variable and $X\geq0$ is another random variable, then how do you determine $E(X\mid U(1-U))$?

    It depends on what you know about $X$. So far you haven't given enough information.2012-12-01

    In general, you would calculate the joint distribution of $X$ and $U(1-U)$, and divide by the marginal of $U(1-U)$ to find the conditional. Then take the expectation.2012-12-01

    If you don't know the JOINT distribution, or anything else about the relationship between $X$ and $U$, then you haven't really asked a question.2012-12-01
