### NY Lost Funds

 yi ok, the p's cancel out nicelyTRWBW: no, of course notkmh: 1/10thanks for being patient TRWBW, kmh kmh they do - nice i somehow didn't expect that TRWBW yi: np kmh yi : so you get the same result your book suggests ? yi yes kmh ok yi you get C(7,5) / C(10,6)which is 1/10 if you do all the arithmetic Capso TRWBW: How does the area under a curve relate to probability? kmh Capso : you can use it to define a probability function TRWBW Capso: well if you have a probability distribution say, for a random variable that takes real values, then the odds of if taking the a value a<=x<=b are the area under that curve. kmh Capso : if you norm it to be 1 - look probability density function (pdf and cdf) TRWBW kmh: it's a nice that they cancel, but not totally weird. take for example turning a biased coin into a fair coin by flipping twice and repeating until you get 1 head. then you are using the probability that the first flip is heads given a total of 1 heads in 2 flips is 50/50, regardless of the bias. Capso kmh and TRWBW: Also... why is it that the probability of finding an electron at a point x,y,z is psi^2 ? kmh actually i was wondering why they sais biased coin TRWBW kmh: well that was probably the neat thing, that the bias cancelled out kmh since the computation works for non biased coin too, but then there would be no need for the general computation with p and people would not notice the cancellation TRWBW Capso: mathwise that's just the definition.kmh: think of what i said about turning an unfair coin into a fair coin by flipping it 2 times and repeating the process until you get exactly 1 head.kmh: this says you can turn any unfair count into a 1/10 coin by flipping it 10 times until you get 6 heads, and seeing if the first three were "htt"webito: check http://en.wikipedia.org/wiki/Linear_differential_equation, look under homogeneous JIMJONESBALLIN hefty, can I help you?or do you just know how the lyric goes, and find it funny? hefty the latter TRWBW JIMJONESBALLIN: just wondering, is your name some kinda reverse marilyn manson, with the mass murderer first and the movie starlet second? JIMJONESBALLIN I wish there was a way I could write it so that it SOUNDS like when he says it.No its a reference to this horrendously bad NY hiphop artist Jim Jones. And he has this track where a guy comes on intermittently throughout the song and goes "BALLIN" hefty JIMJONESBALLIN add more L'sactually more N's JIMJONESBALLIN But he says it in a strange way. like "BAUHLLLLLLLLL-EN" hefty rofl hd770 haha someone used to use that name in tribes hefty yeahBALLLINNN TRWBW k, thought it was "jim jones" the kool-aid killing cult leader + mabel ballin, the silent movie star hefty man we say that all the time at the park where i worklol what an interpretation of the name
