In reality, the odds of guessing heads or tails correctly aren't as even as you might think, and the reason has much more to do with physics than probability.


It's also how you flip it. I can make it flip whatever way I want it too.

nothing is more random than srand(time(null));

Coincidence does not exist people.
Everything is determined, stop kidding yourselves.

The only problem is, we don't always know all the factors of an equation to get the result and hence look into the future.

That's like saying someone is more pregnant than another pregnant person (as my former biology teacher would put it)...

Randomness is something that's either TRUE or FALSE.
As genuine randomness does not exist, it's always false (0) and 0 cannot be more than 0.

I do see how it may be quite good in terms of scrambling the guessability of the result.

The study is BS, or at least the conclusion doesn't apply to toast.

Flipping a coin isn't an even bet either if the person flipping the coin knows how to flip it properly and account for initial position and time spent in air.

For some reason or other I can account for the above-mentioned while flipping a quarter and make it come up heads almost every single time. I'm not sure if it has something to do with observation or the difference in weight on one side vs another...but I can do it...

Then again I can also toss playing cards with a strange level of accuracy as well.

No, nothing is determined, but everything is possible.
