.I'm trying to find how'd you calculate the number of guesses required to correctly guess a 10 digit password made up of numbers only?

Binary or decimal both ok, I just want to learn how'd you calculate it.

I think the probability is ## 1/3628800 ##

take binary case:

For guessing the first number correctly, you'd require 2 guesses.

##2^{10}## guesses

Is this approach correct? ##10^{10}## guesses to guess 10 digit decimal number?
