The coin toss theory has been many an interesting and argumentative discussion.
Even if you flick 15 heads in a row, lock it up for years or do it in 5 minutes, use the same person or 15 different people, the odds on the next flip is still 50-50.
This is because the coin has no memory....but...
Law of odds do,
therefore over whatever time, by whoever, the coin will become closer to 50-50 the more times it is flicked...so
If you've had many heads in a row, at some time, not necessarily the next flip or the next several but at some time/flick/event it will have to pull in (close to) the equal amount of tails.
(this even includes whether one side is decimally heavier than the other)
The same rules apllies to the Roulette table, even though they have 1 green/neutral or 2 on european tables, this is why they have a minimum outside bet rule followed by a maximum to prevent people from (constantly)winning this way. This swings the odds in the houses favour by around 2%, this means that you will win small amounts most of the time, but at some point the ball will give 12 reds/blacks busting the player.
(above example uses doubling up method and is proved to work - scientifically and actually, hence why casino's have moved the goal posts to prevent it) |
