Do you go to school in Canada? Is it free?

yeah I go to school in Canada... It's mostly free off of a scholarship... I only really pay for my books and parking... By my 4th or 5th year, I may be needing to pay a little.

AND GET THEM ALL WRONG!@!!! NO i WASNT TRYING TO EITHER....HOW AMAZING IS THAT...HAPPENED 3 YEARS AGO...STILL AMAZES ME. i REALLY WANT TO KNOW WHAT THE ODDS OF THAT ARE.

LOL, I should be solving this for you... we did have a probability section on our exam.... But ours was even easier than this.. I think the prof just wanted to make sure everyone got some points.

I had to laugh at this thread, and then cry.

We weren't allowed to use calculators in any calc course here.

Well if you take each question as an independent trial, the odds for getting each question wrong is .5 or 50%. The probability of getting two wrong is .5 * .5 or .25. For n number of questions, the probability of getting them all wrong is .5^n....for 10 questions that comes out to .00098, or ~.098%, less than a tenth of a percent.

Keep in mind that is for completely random guessing, with no pattern in guesses, no inclination to a correct answer, nothing...that's simply the probability for flipping a coin and going with it. As far as you actually trying on it, good lord, that's all I have to say.

And was the calculator you bought a scientific calculator or a graphing? Like a TI-86 or something?

I bought a cheap $15 scientific one.

I lost an older model of the TI-86.... like a TI-83 or something like that... Forget the exact name but it was the older model.

so what are the odds...like 1/???

they said the odds of picking the NCAA tournament 100% right is less than getting hit by lightning twice in a row.

½^10 = 1/1024 = 0.0009766 = 0.09766%

I think its funny when the teacher tells a kid that even if he takes the exam hes not gonna pass. but for sure hope, the kid shows up and takes it anyways.

its just 1 in 1024...no way....its gotta be higher than that......because like figuring the odds of the lottery...you have to take into consideration that every time i re-take my quiz (buy a new lottery ticket) the answers are going to randomly change to (like the lottery ticket)

 

[swimfreak26 10+ year member]

it's one in 1024...learn some math man

EDIT: good deal, you figured it out

It wouldn't by any chance have been a math test would it?
