bloodhound Posted April 21, 2004 Share Posted April 21, 2004 When u flip a coin . there are three possible events E1= Head E2=Tails E3=landing on its side now P(E3) must be really small. but even if its small, imagine the number of times coins have been flipped!!!. there must have been a coin landing on its side. Just wanna know if there is any record of that ever happening. Link to comment Share on other sites More sharing options...
Sayonara Posted April 21, 2004 Share Posted April 21, 2004 Isn't there also a chance it will be intercepted and swallowed by a labrador? I'm pretty sure that has probably happened in the past. Link to comment Share on other sites More sharing options...
YT2095 Posted April 21, 2004 Share Posted April 21, 2004 c`mon Sayo, that`s hardly helpfull to the chap try some of these, they MAY be uselfull: http://users.frii.com/davejen/coin3.htm http://mathforum.org/library/drmath/view/52225.html and this one just for fun: http://sln.fi.edu/fellows/fellow7/mar99/probability/gold_coin_flip.shtml for further searches try in google: "coin landing on it`s side" probability and: "coin landing on its edge" probability Link to comment Share on other sites More sharing options...

Dave Posted April 21, 2004 Share Posted April 21, 2004 rofl When you actually think about it, there's almost an infinite number of things that could happen to the coin - most just have infinitely small probabilities Link to comment Share on other sites More sharing options...
Sayonara Posted April 21, 2004 Share Posted April 21, 2004 Oh yeah, and mine isn't helpful even though it's a possibility and can have a p attached to it, but terrosists attacking the coin is at all likely. YT, my post was directing bloodhound to the fact that he said there are "3 possible events" rather than stating that there are 3 landing outcomes. I'd rather leave it up to him to decide if that's a useful pointer to him or not. Link to comment Share on other sites More sharing options...

Sayonara Posted April 21, 2004 Share Posted April 21, 2004 That came much later in the thread and related to a DIFFERENT aspect. Missing the point: Priceless. He did at the end of his post clarify that his intention was about the landing of the coin and not what happened in mid air! Exactly which phrase says that to you? Actually don't bother answering that or this is just going to degenerate into one of those interminable lengths of straw. The fact is you made a judgement about the value of my post without actually understanding why it was there. I don't see any point arguing over it.

bloodhound Posted April 21, 2004 Author Share Posted April 21, 2004 dont blame each other . Blame me!!! anyway thnks for the answers. gonna toss a coin 100000000 times and see if i can get a result.(i dont think ill live long enough to do that) Link to comment Share on other sites More sharing options...
YT2095 Posted April 21, 2004 Share Posted April 21, 2004 it wasn`t your fault at all but as you`ll see in one of those links I gave you, there is a method to work out the probability of an edge/side landing Link to comment Share on other sites More sharing options...
swansont Posted April 21, 2004 Share Posted April 21, 2004 the daftest one I encounted and quite satirical was flipping the coin and having it attacked by terrorists Assuming this happened randomly, would it affect the outcome of the flip?

YT2095 Posted April 21, 2004 Share Posted April 21, 2004 Assuming this happened randomly' date=' How could it not? LOL would it affect the outcome of the flip? I would certainly expect so, as I pressume it wouldn`t LAND to give an outcome/result as you`ve probably guessed, I don`t know how to do this cut and slice up of quotes still, but the colors are fun Link to comment Share on other sites More sharing options...
Connor Posted January 13, 2006 Share Posted January 13, 2006 I have had a similar thing happen to me. For my stat class, I had to flip a paper clip and see which side ended up ~100 times. Lo and behold, one time it landed on its edge! I couldn't even balance it there when I tried to! totally screwed up my results. Link to comment Share on other sites More sharing options...

rakuenso Posted January 13, 2006 Share Posted January 13, 2006 unless your paper clip has square edges and it just happened to be not rotating while in mid-air, i find it extremely unlikely Link to comment Share on other sites More sharing options...
Connor Posted January 14, 2006 Share Posted January 14, 2006 I am not lying. I was absolutely astounded by it, but it happened, with a normal flip and a normal clip. I couldn't even make it balance like that by placing it. Link to comment Share on other sites More sharing options...

Connor Posted January 14, 2006 Share Posted January 14, 2006 well I oversimplified the problem for clarity, but I think I've just muddled things. It was a bent paper clip (think of an L), and it could land with one side up or both sides on the ground. However, one time I flipped it and neither side was on the ground, but the paperclip was balanced on the tips Link to comment Share on other sites More sharing options...
Lyssia Posted January 15, 2006 Share Posted January 15, 2006 During a maths lesson in primary school in which we were flipping coins and doing other prob-related stuff, my coin landed on its edge. The girl I was working with and I just sat there and gawped before telling our teacher, who didn't believe us. It was seen by one other kid, and for the rest of the lesson and the lunch break afterwards the three of us tried to recreate it. Of course it all gets simplified, otherwise prob textbooks wouldn't talk about P(head) = P(tails) = 0.5. This is why I prefer something like algebra (in the main): simplifications make me nervous.
