<p>i love this</p>
<p>from the book: The Drunkard's Walk- How Randomness Rules Our Lives
by: Leonard Mlodinow</p>
<p>excerpt:
"At Duke University, two students had received A's in chemistry all semester. But on the night before the final exam, they were partying in another state and didn't get back to Duke until it was over. Their excuse to the professor was that they had a flat tire, and they asked if they could take a make-up test. The professor agreed, wrote out a test, and sent the two to separate rooms to take it. The first question was worth five points. Then they flipped the paper over and found the second question, worth 95 points:"which tire was it?" What was the probability that both students would say the same thing?"</p>
<p>haha busted
but, they have a 1/4 probability of choosing the same tire, according to the book</p>
<p>wow, i am such a nerd</p>
<p>^^^Haha, that really cracked me up. Good one. :)</p>
<p>you guys should read that book!!!</p>
<p>lol.</p>
<p>"I was so emotionally distressed that I never saw which tire it had been"</p>
<p>hahah and have u guys heard of the monty hall problem???</p>
<p>haha well, i will explain the monty hall problem to you guys!!</p>
<p>let's say this:
you're on a gameshow and there are three doors. one door has a sparkling red ferrari, and the other two doors have "complete works of shakespeare in Serbian"(lol had to say that, thought the example was hilarious). people would probably want the ferrari right?
so let's say you pick door one. then the host opens door 2 and shows you that it's shakespeare. are you better off switching your choice to door three or stick with door one?
well, probability wise, you would have a better chance of winning the ferrari if you switched to door three. </p>
<p>this sounds absurd, but here's an explanation.
your chances of winning the ferrari is 1/3
your chances of not winning the ferrari is 2/3
so you're more likely to guess wrongly in the first place
because of this, you're better off switching</p>
<p>"statistics from the tv program bear this out: those who found themselves in teh situation described in the problem and switched their choice won about twice as often as those who did not"</p>
<p>if you're still skeptical about switching doors, think about it like this. </p>
<p>let's say there are now 100 doors, and the ferrari is behind 1 door.
you have a chance of 1/100 of picking the correct door.
let's say you chose door 46. the host opens every door to reveal copies of shakespeare except door number 23.
are you better off sticking with door 46, or door 23??
obviously, you have better chances of winning if you switched to door 23.</p>
<p>c'mon people! read this! i don't want to talk to myself hahahah</p>
<p>i find this intriguing!!!!</p>
<p>Oh, I do too!!!</p>
<p>Probability is the best!! Woo!</p>
<p>^ aww is that sarcasm??</p>
<p>mperfectionist, is your location related to the book 1984???</p>
<p>Yes, I love 1984 and George Orwell! Oscar Wilde and Allen Ginsberg are also a few of my favorite peoples. </p>
<p>And, no, it's not sarcasm. I'm sorry if it came off like that. I truly do enjoy math, especially trigonometric functions. <3</p>
<p>ahhh!!! really??? i love that book too!!!</p>
<p>I hate probability.. I can never grasp it because I overthink it.</p>
<p>There are 2 lollipops and 3 mints in a bag.
What is the probability that you pull out a lollipop?</p>
<p>Okaaaay it is 2/5.
BUT it really depends on which one you want. Do you want a lollipop or not? They obviously feel different, so you're going to pull out whichever one you want.
On the other hand, the lollipop has a larger volume than the mints, so shouldn't that be taken into effect?
BAHAHWLKFJA?!
I hate probability...</p>
<p>^^^^Ahh! I feel your pain.</p>
<p>lol i'd rather have the lollipop</p>
<p>do u guys understand the door probleM??</p>
<p>Seriously, I'd rather have the lollipop too, so it's obviously 100% chance that you pull that out. But that answer is always wrong for some reason.. haha</p>
