"easy" maths question

[raaaid]

how many SUCCESIVE (average )tosses of a coin you need to get two consecutive tails ?

[WTE_Galway]

just two if your luck is in ...

however it may not work every time you try



... or 6 if you want a real answer based on limits.

work out the angle of launch, the amount of energy involed in launch, the length of launch (travel), the flick required at the end of travel of launch (well in this they have to spin) allow for atmospherics, inebriation, calls of cheat and tolerances of launch factors which would also be required... the math ain't easy

and if you tried all that at a two-up game, you'd be "taken out the back"

exactly i wouldnt expect less from this comunity

but thats what maths say, the same maths that say you cant fly in dreams

check this out:

http://www.random.org/cgi-bin/randby...16384&format=b

total number of digits: 16384*8=131072

total cuts for end line :16384:8=2048

efective digits to count: 131072-2048=129024

times than 11 appears: 20028

times than 1_1 appears: 3649

total times that 11 appears 20028+3649=23677

so how many digits you played to get 11?

129024:23677=5.458 not 6

maybe a sample not big enough

or more likely imo we decieve ourselves to see what we expect to see

on a more wishfull rational thinking a pseudorandom number is not the same than a true random number, a pseudorandom is expected to fullfill statistics and 11 will appear every six digits, on a true random every 5.5

edit:

amore likely posibilty is that this site:

http://www.random.org/

actually doesnt produce true random numbers

but if i found a bias on that site coundt find as well a bias on the PSEUDO random generator of the ONLINE casinos?, as a matter of fact i think i just did as well in an online casino playing with no money, that site 11 repeats more than it should this casino seems to does it less than it should

Also remember that real world coins do not flip with a 50% chance. When flipping a real coin there is a bias towards the heavier side of the coin (usually the heads side) ending up facing down.

well dont you understand the apealling of trying the imposible?

my objectives are:

build a selfstable inverted pendulum, imposible from statics

find a way to beat roulette, imposible

achieve enlightenment by training uncouncious funcionts of the brain like eye accomodation, imposible but already did some imposible thing with my perception like seeing as perfect with the peripheral view as with za<central

as a matter of fact i guess its in my genes, everybody said solving fermats theoreme with classsical maths was imposible, my dad tried and succeed but got no merit for it as it had been solved by willes with modern maths before

i tell him that if he had tried a way to beat roulete as i do and solved it it would have been more usefull
