Yes, it's always 50/50 on any coin toss that's elementary.....sooooo if it's always 50/50 then 200 heads in a row is just as conceivable as 1? Yes?



NO. Yes the odds of a head in a single toss are 50/50....DJ and Mission are also correct that past results do not affect future outcomes, so that the odds of the 200th flip are also 50%. But for that to occur the first 199 flips must be heads (highly unlikely). Consider that for a coin to come up head 200 times in a row. You have to have it be heads every time. So 1st flip Heads...odds 50%...second flip Heads 50% of the ALREADY FLIPPED COINS THAT CAME UP HEADS the first time so 25%; third flip 50% of the 25% or 12.5%...(.50x.50x.50 =.125 get it?)...repeat this as much as you'd like.

Don't confuse individual events with a series of events. So if you walk by the Roulette Table and it's been red 199 times in a row. BLACK IS NOT DUE!!

Having said all that; in the unlikely event I saw a roulette table hit Red 199 times in a row...I'd own the casino.

So, could it be said Roulette, for example could be viewed as a series of events vs. individual events?

Sure. But the events in that series have no impact on each other.

1 head in a row is going to happen 50% of the time

200 heads in a row wont ever happen .5^200, not sure of exact answer but it looks something like this 0.000000000000000000000000000000000000000001%
(it will actually be quite a few more zeros that what i showed)

100 heads in a row is around e-30 (30 zeros)


but if you are asking what do i think the probability of the next flip being heads or tails? 50/50 man, always

Here is an engineering trick.

2^10 = 10^3 (approximately -- to 2 digit accuracy, 1000 vs. 1024). This is very useful for making approximations of the number of digits in a power of 2.

So, in this case, 2^200 = (2^10)^20 = (10^3)^20 = 10^60, so there are about 60 digits. In other words, 200*(3/10) = 60.

You can view it however you want, but the casino only accepts bets on individual events. There is no way to book a wager that the next 200 spins will be red, or on any other series of bets, in a standard roulette game.
