Goth test Odds

I was recently informed of the odds of passing the goth test....

whoever said that there are 30 ways of taking the the test and that there is 1 in 30 chance in passing is wrong. it is a permutation which means that out of a possible 30 answers, you must pick 10 in the correct sequence, so that if someone or a computer did it randomly, there would be 30C10 chance of passing. for those of you who don't understand this, that's one chance in 30,045,015. That's over 30 million.

While this may or may not be the odds of passing it right the first time if you can't read and have an IQ of... say... a lemming.... This is not how many questions you have to answer to pass the test.

The test tells you at the end how many you got wrong. So, since each question has 3 answers - assuming you guessed randomly, you should get around 33% right the first try (this is the first 10 answers). But it doesn't matter, since you can then go through systematically and change one of your answers each time through and see if your score goes up or down. If it goes down, you had it right, if it goes up, you just got it right, if it doesn't change, try the other one. That means you answer 10 questions each time to get your score, and you can change each answer 2 times (since you used one answer for your baseline score), wich is 10+10^2, not 30C10 (30,045,015). 10+10^2 is 110

My incorrect statement that 30 questions was the most you should need to answer to pass was not about the chances of getting it right the first time. It was how many tries it should take to pass the test if you cheat and trick it into letting you take it more than once in a day. This is also the worst possible case, the odds are actually significantly better since when you change your answer for a question, you have a 2/3 chance of determining the right answer (not of choosing the right answer, but it doesn't matter since you'll know which one's right and can move on to the next question)

All of this assumes you don't understand what you are reading, it doesn't take into account that at least a third of the questions are obviously idiot bait. This should bring the effective number of reasonable choices back down to 6.6+6.6^2 which is about 50 answers to pass.

And whether they pass or not it still doesn't explain why people are answering 519 questions on a goth site just so I can validate them as goth.

(NOTE: since that was written, questions have been added to the test, so there are now 12 questions, which means 12+12^2 or 156 possible answers before passing if you can't read).

Anyone disagree? Anyone wanna go to vegas?
