    Mixed Random Variable

    Do mixed random variables show up on exam p frequently.
    I can't seem to wrap my head around it.

    How can a variable be both?

    They do from time to time. I'm not sure what you mean by how? I can assign a fixed mass to a point and then anything outside that point vary according to some random distribution.

    There's at least one sample question for 1/P that has a mixed distribution, you should go through those sample questions and know how to do all of them before attempting the exam.
