The question.......what should you do?

If I recall correctly, you should change your mind. When you chose the
first, you had a 1/3 chance of being right, and nothing has changed that.
If you change your mind now, that gives you a 2/3 chance of being correct.
I'm pretty sure I'm dead wrong on that 2/3 number, though, but the chance
is more than 0.5.

Actually, I believe your exactly right about the 2/3.

Um.....well, it's been a couple hours since I last looked at the
solution, so I could be wrong.

The key is that the removal process is not random.

Yep.
