    Discrete Random Variables

    "Let Y denote the duration, to the nearest minute, of a total solar eclipse. Is Y a discrete random variable?"

    This is one of my homework problems. There is no list of values to choose from. Can time be a discrete random variable and can it be discrete random variable if there are no values to choose from?

    Thanks!

    The duration of a total eclipse can be calculated to better precision
    than 1 minute for any location on the path of totality. So no.

    But if you don't know where you are on the path it could well be regarded
    as a RV. So the answer is yes.

    Life does not consist of a sequence of multiple choice questions.
