Password possibilities question

How does one determine the number of possibilities for guessing a password?

E.g. say I have a 8 character password and each character can be one of 62 characters (alphabet uppercase, alphabet lowercase and numbers 0-9). Does this mean ( to somebody who might want to guess the password) that there are 62^8 (thus 218 340 105 584 896) possible combinations?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

don't forget the 15 Ascii charachters as well.  this would give the number possible password combo's as 77 to the 8th power

77x77x77x77x77x77x77x77 = total

YES  77^8

Yes that is correct, but the possibilities can be increased further  by allowing for  any addtional ascii characters  such as puntuation and symbols, aswell as Ctrl Characters to expand the range of combinations..
