Definitely depends on where you are fishing.

There is a dam where I would fish at a lot... Rocky bottom where a hook can catch quite often. If I fished via bobber there, I wouldn't lose many hooks at all. Fishing from the bottom, would easily lose a few.

All depends on the strength of your line as well. If you are stringing a line across a stream, you should be fine with a few hooks...

Hooks are sinkers are small, pack a bunch... Don't worry about bobbers tho, sticks work fine for that.
