| thatgraemeguy | morning peeps | 07:32 |
| inetpro | good mornings everyone | 07:37 |
| inetpro | oh and hi thatgraemeguy and pieter2627 | 07:37 |
| pieter2627 | o/ inetpro | 07:37 |
| Sxuza | so why is there so much noise here today ? | 09:07 |
| Sxuza | Cryterion : morning | 09:07 |
| Sxuza | u got my sms the Saturday ? | 09:07 |
| Sxuza | did the work thingie go well ? | 09:08 |
| Cryterion | Morning, Sorry was very busy over the weekend with family and didn't get a chance to contact you | 09:11 |
| Sxuza | no problem | 09:12 |
| Sxuza | but u did come down to EL ? | 09:12 |
| Cryterion | Yes did, but had to return yesterday | 09:13 |
| Sxuza | o ok | 09:13 |
| ghostcomplex | hmmm | 10:48 |
| ghostcomplex | hi guys, any stats fundies here: | 11:04 |
| ghostcomplex | If I win 70% of my matches and you win 60% of your matches, how you you calculate the probalibity of me beating you? | 11:06 |
| MaNI | the probability of you beating me is always 0 | 11:16 |
| pieter2627 | i think it would be 70 over 60 | 11:35 |
| pieter2627 | gremble would be best at answering that as far i know | 11:37 |
| ghostcomplex | MaNI: Why do say 0 | 12:08 |
| MaNI | I cannot be beaten :) | 12:09 |
| MaNI | nah j/k I also think it would be 70 over 60 but I'm too tired to think properly at the moment :p | 12:10 |
| ghostcomplex | hmmmm | 12:17 |
| ghostcomplex | do you perhaps knwo what kind of topic this problem will fall under? | 12:18 |
| pieter2627 | ghostcomplex: (statistical) probability... | 12:24 |
| pieter2627 | here is my thinking behind it: | 12:25 |
| pieter2627 | Imagine 4 teams that will play against each other... | 12:25 |
| pieter2627 | that is three matches per team as you don't play against yourself... | 12:26 |
| pieter2627 | team A and team B has played two matched (against C & D) and will now face each other | 12:26 |
| pieter2627 | Team A has won both (100%) | 12:27 |
| pieter2627 | team B one (50%) | 12:27 |
| pieter2627 | then try working it from there | 12:29 |
| * pieter2627 just cannot completely find why 100 over 50 seems ok | 12:31 | |
| ghostcomplex | I'm also struggling to understand the 100/50 part, hence trying to find the topic, thanks pieter2627 | 12:32 |
| pieter2627 | yea it is quite complex - can't even think of it as a venn diagram | 12:34 |
| * pieter2627 just realised that it will be wrong - if both had 50% then the probability for each has to be 50% | 12:36 | |
| ghostcomplex | true pieter2627 | 12:38 |
| ghostcomplex | also having trouble googling the problem | 12:39 |
| magespawn | good afternoon | 12:40 |
| ghostcomplex | hi magespawn | 12:43 |
| ghostcomplex | perhaps you can help: If I win 70% of my matches and you win 60% of your matches, how you you calculate the probalibity of me beating you? | 12:44 |
| MaNI | P(A ∩ B) = 0 is what you want | 12:54 |
| MaNI | ergh no not even | 12:55 |
| MaNI | key term to search for is mutually exclusive or disjoint though I think | 12:58 |
| MaNI | P(A or B) = P(A) + P(B) = 0.7 + 0.6 = 1.3; 0.7/1.3=0.54 - I believe you can just do that though I'm ready to be corrected :) | 13:05 |
| ghostcomplex | MaNI: Do you perhaps have to link to where you got that from? | 13:15 |
| MaNI | https://people.richland.edu/james/lecture/m170/ch05-rul.html | 13:19 |
| MaNI | see the specific addition rule | 13:20 |
| MaNI | "When two events, A and B, are mutually exclusive, the probability that A or B will occur is the sum of the probability of each event." | 13:23 |
| MaNI | I think you can just plug the numbers into that rule and then balance the equation, the result also feels right to me | 13:24 |
| MaNI | however my statistics knowledge on this sort of thing is a bit rusty so I may be wrong | 13:25 |
| pieter2627 | plugging a 50% 50% (or any other equals) in that also works as expected | 13:26 |
| ghostcomplex | weo weo | 13:27 |
| ghostcomplex | thanks MaNI, that looks correct | 13:28 |
| magespawn | ghostcomplex: i would have to look it up. a little beyond my current level | 13:30 |
| magespawn | there are a couple of the others are mathematicians | 13:31 |
| magespawn | chat later all | 14:06 |
| Kilos | evening superfly and others | 16:22 |
| superfly | Hi Kilos | 16:25 |
