    Am I missing something very obvious?





    I'm not sure why P(X=1) is not 1/6
    For a continuous random variable P(X=x) = 0 for all x.

    But I thought we assumed it was a continuous uniform distribution?

    The fact that this is a continuous distribution so that P(X=x) = 0

    No we didn't. It says it the question, "A continuous random variable X..."

    The continuous distribution means that a fixed value has no probability. If you think about the normal distribution, you always do calculations on a range of values. The reason it doesn't work for one value, is because the line you extrapolate from can be infinitesimally thin so it doesn't have a single value.
