    The inverse normal distribution?

    Using this equation:

    Let:
    n = 3
    p = 0.05
    q = 0.95

    HOW in the world are you supposed to solve for x by hand? I can do it using a calculator but... by hand?

    I can simplify it somewhat but there all these exponents and I'm not sure what to do... do I use a log? And then there is a (3-x)! and I have no clue what to do with that.

    Any help would be much appreciated!

    Are you expected to simplify by hand the expressions you get by substituting these values and values for x. If so, then it looks like you better start practising how to calculate factorials and do multiplications.
