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!
