What percentage of visible stars in the sky are contained within our galaxy?

By "visible" I mean able to be seen by an unaided human eye in a very good star gazing location, i.e. not near any cities or sources of light. Just wondering, a ball park number is fine, but please provide some sort of proof.

    There are roughly 200 billion stars in our galaxy. Not all can be seen with the unaided eye - but all teh stars we see at night are in our galaxy. In the northern hemisphere you can see one galaxy with the unaided eye (Andromeda) but you cant make out individual stars.

    In the southern hemi there are two Magellanic Clouds that are dwarf galaxies that can be seen, but they mainly look like large fuzzy patches in the sky. Both of these dwarf galaxies orbit the milky way.

    sure, in case you do not have binoculars or a telescope. the only exceptions are which you'll be watching the Andromeda galaxy (in case you're interior the northern hemisphere) or the Magellanic clouds (interior the southern hemisphere) that are different galaxies. in case you have binoculars or a telescope, you are able to truly make out different galaxies, yet they're going to look as fuzzy clouds, unlike stars. each and all of the nebulae you will see are in our galaxy (exception for those interior the southern hemisphere: the tarantula nebula isn't in our galaxy).

    About 100% of the stars we see with the naked eye are in the Milkyway galaxy. That's not counting the very weak and diffuse "clouds" of the Andromeda, and the small and large Magellanic galaxies. You can't see individual stars in those galaxies without a good telescope.

    That depends upon what you mean by "visible stars".

    If you mean individually distinguishable stars, then 100% are contained within our galaxy. Other galaxies are too far away to be able to distinguish individual stars.

    If you mean that we see the stars in other galaxies because we know that galaxies are made of stars, then our galaxy contains a very, very, very very miniscule percentage of "visible stars". Just as every individual galaxy contains a very, very, very very miniscule percentage of "visible stars".

    100%. All the stars we see in our sky are in our own galaxy, the Milky Way. We can see a few external galaxies naked eye, but they do not appear as stars, but as small fuzzy patches.

    100% but some of the bright object in the sky may be planets or satellites, also our eye doesn't have the resolving power to see any star out side of the milky way, a lot of the stars you see are binary stars yet they appear to be one point of light.

    All the stars within a 60 light year sphere around earth can be seen with the naked eye.

    All of them. No star in another galaxy is bright enough to see from Earth without a telescope.
