A couple questions, do game engines combine third-party Graphics and Physics engines? And is the majority(above 50%) of a game engine it's graphics engine?

Some do, some don't.

Not even close to 50% - I'd estimate somewhere between 5% to 20% depending on whether you're writing Pacman or Crysis.

For your first question, that depends entirely on who's building the game engine. If you're talking about a developer like EA or id, for the most part they develop their own physics code.

As for your second, the graphics of a game is far from the most important part. While it may be a big chunk (depending on what kind of game you're working on), you've got all of the other systems to think about as well -- GUI, Input, Audio, Physics, AI, etc. Your biggest chunk of code is generally going to be the logic -- things like NPC interaction, AI, weapon trajectories (for projectile based weapons), if you've got vehicles then you've got all of the logic involved for handling the wheels and vehicle physics, etc.
