If you have n rings with r numbers in each ring, then the probability of any particular combination is 1/(r^n). r^n denotes r to the power n.
So, for a typical lock with three rings, and 10 digits in each ring (0-9), the probability is 1/(10^3) = 1/1000.

You have to have a combination. If you have a key lock you don't need a combination, all it is is a lock that says master and a key to turn it and then it opens what you have in it.

If your lock is a resettable kind, all you have to do is make a password that you can remember and save it. If you have a lock that cannot be resettable, look in your locks packet to find the combination or look at the back of your lock to see if it's been stuck there.

A probability must be a real number in the interval [0, 1]. The sum (or integral) of the probabilities over all possible values must be 1.
