    Linear probability distribution

    I am trying to come up with a concise formula for a probability distribution that is just decreasing linearly but it is eluding me.

    What I am looking for is:

    For instance, given uniformly distributed random numbers 0 - 1 I want to map those to 0 - n with 0 having the highest probability and n having the lowest. Seems straightforward but ... Perhaps not.

    Thanks!

    Use the probability integral transform theorem:
