 | | Marilyn says she first took the test in September 1956, at the age of 10 years and 0 months, and achieved the ceiling mental age of 22 years and 10 months, yielding an IQ of 228. |
 | | Marilyn's raw score was 46 out of 48, corresponding in the latest norming of the test to a z-score of 5.4 and therefore an IQ of 186, a percentile of 99.999997, and a rarity of 1 in 30,000,000 (Hoeflin 1989). |
 | | Marilyn's answer, that you should switch because door #2 has a 2/3 chance of winning whereas door #1 has only a 1/3 chance, provoked thousands of letters in response, nearly all arguing that she was wrong and that the doors are equally likely to win. |
