ok, i follow you,
each toss as either 0 or 1, with 50/50 on each toss. 8 continuous toss with all 0 or all 1 is really special. because you can't get this result easily. the most common result are, 0 then 1, or 1, then 0, or a few 1 then 0, or a few 0, then 1 the a few here, i say, less than 5 times. in fact, if i get a coin now, toss it 8 times, or maybe toss it for my whole life, a continuous 10 toss or 8 toss with head/ or tail, might be near impossible.

Each 8sequence of 0s and 1s is equiprobable; we're talking about probability of equivalence classes, i.e. classes of 8sequences with 0, 1,…, 8 1s. Let's see:
There is only one 8sequence with no 1s: 00000000; eight 8sequences with only one 1; as the whole picture goes: Code: 0: 1 * 1: 8 ******** 2: 28 **************************** 3: 56 ******************************************************** 4: 70 ********************************************************************** 5: 56 ******************************************************** 6: 28 **************************** 7: 8 ******** 8: 1 *

baldr&revolution, thanks for bringing some sanity back to this thread. I was starting to get depressed about education standards...what kind of experiments did you try in grade school?
While we are on the topic of probability, does anyone have an answer to my challenge at http://board.flatassembler.net/topic.php?t=15780&postdays=0&postorder=asc&start=20?

welll at first it doesnt quite work got about equal not going too far.. 4050 throws.. basicly.. some of my brainparts can tap into things.. so if i concentrate well and i cann see at least subconsciously the head or tail.. as spinning in air, i flip it up.. then concentrate on the thing.. and it lands.. first i got equial about that.. then i made for quite some time double tails so there was more chance.. then i started making heads deliberately so i made a lot of heads and i wanted it so.. i vsn drr zhr coin.. my subconscious can know arrangement of coin.. so if i concentrate it will more often catch as i need it..
Pretty cool topic. its not so much about logic i think rather it is about throwing skills. _________________ Best location where I Harden, shall be the most beautifull Garden

if it is 50/50,
what is the chances of getting 20 people, to let everybody toss same head/tail at the same time? 50/50 ?

1 in 2^20.

sleepsleep
actually, i am kinda wonder, what percentage of confirmation is that 1 in 2^20?
or, it is a confirm fact? because, i seriously don't think so. another view of this is, if let say a random number generator for 1 to 10,000, and we put a counter for each displayed number. let say, you call it for 10,000 x 10 times, would there be a number still with 0 displayed count?

sleepsleep: Perhaps you should read a book about statistics instead of expecting us to teach you here. This is basic stuff that is explained in all the introductory texts.

ok, sorry with my lack of knowledge with statistic,
a few questions, 1. if after a 15,000 times random procedure was called, and i noted there is a number is still not yet displayed, does it still 50/50 for the next call? 2. so, is there a statistical result different this random number generator with tossing coin?

sorry ...much effort is required in my part to understand this.

yeah, because of the idea, eventually, with some level of certainty, this number will get called. because of another idea, could 10,000 x 10 times and we have a number without being called. regarding the 2nd question, is random a mimic of how nature works? must have a graph of some sort of distribution? or random should be, random, unknown, unpredictable?
