hk213 Posted September 25, 2008 Report Share Posted September 25, 2008 wow..... this investigation that i received today is due in 1 1/2 weeks from now and yet i don't have any clues on how to even start this thing.The investigation is about analyzing the relationship between certain probability distributions and the first part of it asks you to build a model.So its about two players playing Tennis and they play for 10 points- and one person wins about twice as many points as the other person.OK HERE COMES THE PART WHICH I'M COMPLETELY LOST. The instruction tells you to find an appropriate model for the distribution of X, the number of points won by the player who wins twice as many points.So what do you think about this??? what would be an appropriate model fro the distribution??? are there any limitations in terms of its validity???

Vicdashit Posted September 25, 2008 Report Share Posted September 25, 2008 Yo wassup kimchiiii talked it over with vic and we decided that adam has 2/3 chances of winning a point and ben has 1/3 chance of winnign a point. The limitation of this is that the total probability will be 99.99999999999999 but never 100. see u tomorrow hk Reply Link to post Share on other sites More sharing options...

Vicdashit Posted September 28, 2008 Report Share Posted September 28, 2008 also there is no limitations for multiples of 3 Reply Link to post Share on other sites More sharing options...

In the same way that 0.999...=1, not 0.999...≈1 Reply Link to post Share on other sites More sharing options...
xsandralee Posted September 29, 2008 Report Share Posted September 29, 2008 I DID THIS PORTFOLIO. it's fairly understandable/tolerable/do-able up to part II, then, part III makes you want to give up on everything. but basically with the 10 point one, you do the binomial theorem - hopefully you know what that is, where n is the number of total points, and r is the number of points one person can win (so if youre looking for adam's win, then you set it: Adam's probability of winning r=0 points, or r=1 points, etc)and p and 1-p represents , well you can look it in two ways: 1) p = probability adam wins while 1-p = probability that adam loses. OR 2) p = probabilit ythat adam wins while 1-p = probability that ben wins. its very fine, until part III. seriously... Reply Link to post Share on other sites More sharing options...
xsandralee Posted September 29, 2008 Report Share Posted September 29, 2008 btw, i'm not sure i agree with the limitation. the limitation is that this is a MODEL, using perfect conditions - meaning, it gets rid of all extraneous varaiables/values that can affect the outcome. for example, illnesses, weather conditions, etc. you know?

xsandralee Posted October 1, 2008 Report Share Posted October 1, 2008 i handed my portfolio in yseterday, so if you need any help just post : ) I'll try to answer asap. Reply Link to post Share on other sites More sharing options...
Vicdashit Posted October 3, 2008 Report Share Posted October 3, 2008 Yea part 3 is getting to the point where it is nearly impossible any pointers to lead me onto the right track? Reply Link to post Share on other sites More sharing options...
MFCF Posted October 16, 2008 Report Share Posted October 16, 2008 I just start doing that...i totally forget anything about probability, hope i can find the support here...thanks Reply Link to post Share on other sites More sharing options...
finqui Posted November 11, 2008 Report Share Posted November 11, 2008 Could somebody give me some hints about how to study Part III? My perfect binomial theorem has been destroyed Thank you in advance Reply Link to post Share on other sites More sharing options...
bellavida Posted February 28, 2009 Report Share Posted February 28, 2009 Could somebody give me some hints about how to study Part III? My perfect binomial theorem has been destroyed Thank you in advancehave you figured it out yet? I am in desperate need of help with part 3 - any hints please? ive read over and over that question 6 helps with 5, but i still don't see how to work out the odds since the games could theoretically be infinitely long..

moneyfaery Posted February 28, 2009 Report Share Posted February 28, 2009 have you figured it out yet? I am in desperate need of help with part 3 - any hints please? ive read over and over that question 6 helps with 5, but i still don't see how to work out the odds since the games could theoretically be infinitely long..Infinite geometric series. I swear that's been stated a few times now. Reply Link to post Share on other sites More sharing options...
cinjee Posted April 11, 2010 Report Share Posted April 11, 2010 (edited) could someone explain the question c in part 1?what does it mean by "what can you say about what usually happens in these 10-point practices?"do i have to sorta say something based on the histogram? or i can just describe the histogram and predict what would happen accordin to it.thank u in adv.
