Probability based puzzles are always confusing (of course for me).

I have a set of puzzles, this is the fist of the seris (I am sure you might have solved these already).
I can look around for answers but I need reasoning (that what I am looking for here).

Ok now the puzzle.

You are playing a game of fortune. There are 3 doors (closed) say A, B and C. One door hides a car and rest Goats.
At the beginning of the game, Quiz master asks you to pick one of the doors.

Quiz master is kind enough and opens one of the other two doors (that are not picked by you) that reveals a Goat.
Now there two doors unopened, one you chose initially, and other picked by the Quiz master.

If you were given chance to choose either of the unopened doors, will you change your initial choice? why?

Thanks
