As you can see, having the letters in the game repeat makes for a much more challenging game. Let’s keep the game the way it was originally designed, with three doors and the possibility of the letters repeating.
What’s Behind the Door?
If you can guess the letter behind the door, you win a prize!
Large Prize:
Guess all three doors correctly
Medium Prize:
Guess two doors correctly
Small Prize:
Guess one door correctly

These probabilities are the theoretical probabilities. Theoretically, a person should win a small prize twice as often as a medium prize, and approximately 50% of the time a contestant wins a small prize. Seldom should a contestant win a large prize.
Let’s conduct a probability simulation to see if these theoretical probabilities hold true!
