當初的爭議可以看這一段
=======================================================================
A restated version of Selvin's problem statement appeared in Marilyn
vos Savant's "Ask Marilyn" question-and-answer column of Parade
magazine in September 1990. Though vos Savant gave the correct answer
that switching would win 2/3rds of the time, vos Savant estimates
10,000 readers including several hundred mathematics professors wrote
in to declare that her solution was wrong. As a result of the publicity
the problem earned the alternative name Marilyn and the Goats.
=======================================================================
在1990年Marilyn vos Savant曾經在雜誌專欄裡提過這個問題，並給了換了之後
可以贏2/3的正確答案。不過之後卻接到了約一萬名讀者(其中包括幾百位數學教
授)聲稱這個答案是錯誤的來信。
