Well at least we're willing to admit it.

Congrats, though I too had to find out what it was

Congrats!!

thanks, google and wikipedia!

Kickass dude! Am I the only one who knew what it was? Didn't y'alls have to take statistics in college?

BizB · « **Reply #9 on:** February 25, 2008, 07:08:27 PM »

I knew, but I wasn't as impress as those who posted above.

Still, j0rb w3ll d0n3.

What are the odds, eh?

Don't answer that!

Grats!

Seriously, what are the odds?

Jaepheth · « **Reply #13 on:** February 28, 2008, 02:08:01 AM »

It's really hard to say.

The inner workings of how the exam is graded is mostly kept secret.
What is known is that The Society of Actuaries determines a certain pass mark, and the exams meeting that requirement pass.
Exam P consists of 30 multiple choice probability questions with 5 options each, and you have 3 hours in which to complete them. The questions are drawn from a pool of questions. Since the questions are reused from year to year, the probability of getting a specific question right is statistically known. If you draw a lot of easy questions you must answer more of them correctly to pass, or if you draw a lot of hard questions you need to get fewer of them correct.
I'm also told that some questions are being tested and so are thrown into the question pool in order to get the probability of people getting them correct. These questions don't count toward your score, and there's no way to tell it from a question that does count.

But if you assume 30 equally weighted questions with a probability of 1/5 of getting any one right (random guessing) and a 60% needed to pass (18 questions right) then the probability of passing is (1 - the binomial CDF at 17). On the exam, I'd approximate it with a normal distribution and continuity correction with mean 30*1/5 and variance 30*1/5*4/5, but now I can use a spreadsheet with a binomial function, and it tells me that the probability is 1.842*10^-6

Making the odds 542,755 to 1 against.

But if you study enough to make the probability of getting any 1 question correct .5, then the odds improve to about 5 to 1 against

well, there you have it.

Math talk!! You're gunna make Detta get all hot.

Don't get all radical on us.

Dark Shade · « **Reply #17 on:** February 28, 2008, 09:22:35 PM »

Time to prime up for another one of these threads.

Jaepheth · « **Reply #18 on:** February 29, 2008, 05:38:07 AM »

What do you mean?

ivan · « **Reply #19 on:** February 29, 2008, 11:49:34 AM »

No. Threads such as this are divisive.

Jaepheth · « **Reply #20 on:** February 29, 2008, 12:39:30 PM »

But they're an integral part of the board's identity.

ivan · « **Reply #21 on:** February 29, 2008, 12:50:04 PM »

Dude, don't be irrational. We must strive to maintain a positive, well-rounded environment here. Pun threads are but a fraction of the overall content, yet their negative impact is disproportionately lar...

waitaminute... that's not punning -- that's MATH TALK!

pbsaurus · « **Reply #22 on:** February 29, 2008, 01:27:38 PM »

It could just be imaginary.

Min · « **Reply #23 on:** February 29, 2008, 05:53:28 PM »

Weeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee!!!!

Love it.

I knew what it was, cause I took that test. And it was fucking hard.

Min · « **Reply #24 on:** February 29, 2008, 05:54:44 PM »

Also, we had a quiz on simplifying radicals the other day. On the board, in the list of things to do today I put, "Totally Radical Quiz". They weren't that amused.
