[06:36] morning all [07:32] morning peeps [07:37] good mornings everyone [07:37] oh and hi thatgraemeguy and pieter2627 [07:37] o/ inetpro [09:07] so why is there so much noise here today ? [09:07] Cryterion : morning [09:07] u got my sms the Saturday ? [09:08] did the work thingie go well ? [09:11] Morning, Sorry was very busy over the weekend with family and didn't get a chance to contact you [09:12] no problem [09:12] but u did come down to EL ? [09:13] Yes did, but had to return yesterday [09:13] o ok [10:48] hmmm [11:04] hi guys, any stats fundies here: [11:06] If I win 70% of my matches and you win 60% of your matches, how you you calculate the probalibity of me beating you? [11:16] the probability of you beating me is always 0 [11:35] i think it would be 70 over 60 [11:37] gremble would be best at answering that as far i know [12:08] MaNI: Why do say 0 [12:09] I cannot be beaten :) [12:10] nah j/k I also think it would be 70 over 60 but I'm too tired to think properly at the moment :p [12:17] hmmmm [12:18] do you perhaps knwo what kind of topic this problem will fall under? [12:24] ghostcomplex: (statistical) probability... [12:25] here is my thinking behind it: [12:25] Imagine 4 teams that will play against each other... [12:26] that is three matches per team as you don't play against yourself... [12:26] team A and team B has played two matched (against C & D) and will now face each other [12:27] Team A has won both (100%) [12:27] team B one (50%) [12:29] then try working it from there [12:31] * pieter2627 just cannot completely find why 100 over 50 seems ok [12:32] I'm also struggling to understand the 100/50 part, hence trying to find the topic, thanks pieter2627 [12:34] yea it is quite complex - can't even think of it as a venn diagram [12:36] * pieter2627 just realised that it will be wrong - if both had 50% then the probability for each has to be 50% [12:38] true pieter2627 [12:39] also having trouble googling the problem [12:40] good afternoon [12:43] hi magespawn [12:44] 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? [12:54] P(A ∩ B) = 0 is what you want [12:55] ergh no not even [12:58] key term to search for is mutually exclusive or disjoint though I think [13:05] 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 :) [13:15] MaNI: Do you perhaps have to link to where you got that from? [13:19] https://people.richland.edu/james/lecture/m170/ch05-rul.html [13:20] see the specific addition rule [13:23] "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." [13:24] I think you can just plug the numbers into that rule and then balance the equation, the result also feels right to me [13:25] however my statistics knowledge on this sort of thing is a bit rusty so I may be wrong [13:26] plugging a 50% 50% (or any other equals) in that also works as expected [13:27] weo weo [13:28] thanks MaNI, that looks correct [13:30] ghostcomplex: i would have to look it up. a little beyond my current level [13:31] there are a couple of the others are mathematicians [14:06] chat later all [16:22] evening superfly and others [16:25] Hi Kilos [18:09] Hi Kilos how are you doing? Recovery going as hoped? [18:09] Langjan: By the way, Kilos on freenode told me "tell langjan kyk hierna, bietjie snakks maar miskien beter as medikasie http://www.naturalprostate.com/cgi-bin/mailout/mailmgr.cgi" 5 days, 11 hours, 29 minutes and 11 seconds ago [18:09] hi Langjan good ty [18:09] Problem solved? [18:09] hi gremble [18:10] what prob [18:10] oh my, had an op for the kick of it? [18:10] hahahaha [18:10] lmga, is it that good? [18:11] well, noting popping out anymore [18:11] just not lekker when peeps cut holes in you [18:11] but im good ty, how are you [18:12] For sure, not a good thought. Now next step is to get to Oz? [18:12] yes [18:12] Also fine thks, a bit lonely, another week to go. [18:12] want to be there before Christmas [18:13] When are you hoping to go? [18:13] Great, for how long? And where in Oz? [18:13] still some more saving [18:13] melbourne and for 3 months [18:14] Wow! Pretty area, not so far from my girl in Canberra. [18:14] i not going to see the counrty side [18:16] OK visiting, but still beautiful area. So what are you planning to do while you're there? [18:16] sleep [18:16] hahahaha [18:16] expensive sleep... [18:17] and catch up 30 lost years [18:17] Hey Kilos [18:17] Is that how long you have been separated? [18:18] 30 years since first meeting on 31 dec [18:18] ? [18:18] and i suppose 29 and a hlaf since separating [18:20] You met, then separated after 6 months? [18:20] after 4 [18:20] one fight [18:20] and too much arrogance both sides [18:20] that lasted 30 years? [18:21] yeah [18:21] crazy hey [18:21] A better fight than Renamo and Frelimo, they could only do 18 years [18:21] you think i only been stupid since bashing my head [18:21] hehe [18:21] lol [18:22] So what makes you want to get together, both sides? [18:22] both sides [18:22] one wakes up at times to realise that at times there is no alternative [18:23] Enjoyed the fight so much youre ready for another? [18:23] lol [18:23] hahahaha [18:23] So what does she do in Melbourne? [18:23] retired nurse [18:24] And after 3 months, hoping for what? [18:24] well , i spose youll have to wtch this space [18:24] watch [18:25] OK, well I really hope things work out for you the way you would like [18:26] She staying on her own?
