<s>[INST] This problem is a classic probability question on conditional probability, known as the Monty Hall Problem.
**Problem:** Three apples are hidden behind three closed doors of a game show. Anopponent and you are contestants. One of the apples is red, and the remaining two apples are green. The game is played as follows: the game show host generates a random number, number 1, 2, or 3, and the apple behind the corresponding door is your opponent's prize. When the game show host opens a door that has your number on it, you will find an apple: if the apple behind this door is red, you will receive the prize and your opponent will lose the game; if the apple is green, you will first open another door, and after finding the remaining apple, you will get the remaining apple. Otherwise, your opponent will receive the prize. Obviously, the outcome of the game depends on the number of the door that the host opens, which you predicted. Now suppose that you predict the number 1. What is the probability that you will get the red apple?[/INST]
