{In the Monty Hall problem just described, should you stick with your original door or should you switch
After Monty eliminates one door, your chance of choosing the door with the prize remains one in three. The sum of probabilities has to add up to one. So the chance of the prize being behind one of the two doors you didn‘t initially select has to be two in three. Of those two doors, one is open and reveals nothing, so the other has a two in three chance of concealing the prize.}
