Como @ user1118321 apontou, ninguém fez isso porque o jogo não é jogado da maneira descrita no Problema de Monty Hall.
Em 1991, o ex-apresentador Let's Make a Deal Monty Hall criou uma simulação do programa para o repórter do New York Times, John Tierney, e descobriu a falha na tentativa de usar o problema matemático para jogar o jogo. Do artigo do NY Times Atrás Portas do Monty Hall: Quebra-cabeça, Debate e Resposta?
After the 20 trials at the dining room table, the problem also captured Mr. Hall's imagination. He picked up a copy of Ms. vos Savant's original column, read it carefully, saw a loophole and then suggested more trials.
On the first, the contestant picked Door 1.
"That's too bad," Mr. Hall said, opening Door 1. "You've won a goat."
"But you didn't open another door yet or give me a chance to switch."
"Where does it say I have to let you switch every time? I'm the master of the show. Here, try it again."
On the second trial, the contestant again picked Door 1. Mr. Hall opened Door 3, revealing a goat. The contestant was about to switch to Door 2 when Mr. Hall pulled out a roll of bills.
Monty então ofereceu ao competidor quantidades crescentes de dinheiro, parando em $ 5.000 para não trocar as portas. O competidor recusou o dinheiro e trocou as portas.
"You just ended up with a goat," he said, opening the door. The Problem With the Problem.
Mr. Hall continued: "Now do you see what happened there? The higher I got, the more you thought the car was behind Door 2. I wanted to con you into switching there, because I knew the car was behind 1. That's the kind of thing I can do when I'm in control of the game. You may think you have probability going for you when you follow the answer in her column, but there's the psychological factor to consider."
He proceeded to prove his case by winning the next eight rounds. Whenever the contestant began with the wrong door, Mr. Hall promptly opened it and awarded the goat; whenever the contestant started out with the right door, Mr. Hall allowed him to switch doors and get another goat. The only way to win a car would have been to disregard Ms. vos Savant's advice and stick with the original door.
E aqui está a razão pela qual você não pode verificar o Problema de Monty Hall olhando o game show:
Was Mr. Hall cheating? Not according to the rules of the show, because he did have the option of not offering the switch, and he usually did not offer it.
Então, basicamente, é como @user 1118321 disse, o jogo no show não é jogado de acordo com as regras do problema matemático.
