    \[\frac{ 6P5 }{ 6^{5} }\]

    Well, I hope to learn something new today, given the chance that all the people got off at different stories, wanted to go to different rooms, had to go down or up, I'd say that it would look something like... ah, and theres only 5 people so...P=people F+Floor X: starting place Y: Ending place Y=(5f)...and I do not know what dodo from there.

    Well if you count the floor they all get into the elevator on, then there are only 5 other floors left.

    so why didn't we get that solution in the first place?

    The problem statement specifies that there are 6 stories, so there are 6 other floors to go. Therein lies the misunderstanding...

    You have to include all 6 floors. It doesn't say that some weirdo can't ride the elevator up to the top then back down to the first and gets back off.

    right! its all about probability, forget the relativity of the problem

    that's actually illegal and unethical in a lot of countries
