That doesn't make sense, now does it?
And so does the probability of the one you didn't choose. The pool becomes smaller, thus the chance of each box being the prize is increased. Simple. Instead of being 1 of 3 possibilities, each box is now 1 of 2 possibilities. Everything readjusts. 3 has nothing to do with it anymore. 3 doesn't exist anymore in the realm of this problem after the removal of the third box.
