Even with perfect information, the outcome of a probabilistic event, like a coin flip, cannot be known with certainty for the next trial.

“but what I can't know is what it will land on the next try so that's that issue of luck so if you flip and lands heads it's reasonable for me to say it could have landed tails and if we did that again that tails is totally a possibility regardless of what I happen to have seen on this particular flip”
