Fedora 15 is end of life and unsupported. Save the time you would spent for recovery and make a fresh install of Fedora 17 instead.

Why NOT ask why?? That's not a good thing to do.

You can try to boot into single-user mode, and change the permissions/ownership back, or you can boot from CD/DVD into rescue mode, and change it back from there.

Barring that, I'm with TobiSGD...Fedora 15 is old, and if it's broken, performing an upgrade/fresh install to 17 would be good thing.

How, exactly, would she do that, since she CANNOT get in as root to change things back???

This will not help either. The root password is already known, the OP is not able to become root because of borked owner settings in the bin directory.

he/she can boot from a CD and restore permissions

777 is a bad idea in almost all situations. It is a really bad idea with root directories.

You are lucky. I made a similar mistake in my first one or to weeks using Linux. The result was not being able to boot the system. Directories that have root permissions have them for a reason. The best course of action is to follow TobiSGD's advice of up-grading to the current edition of Fedora and do not touch the permissions in your root directory.

I've done similar things before by accident when I was first starting. It was almost always followed by a format and reinstall.
