If there were an exact duplicate of the universe, that started with a big bang that had the exact same conditions, and exploded or inflated the exact same way, etc., quantum events being probabilistic, would events of quantum probability still happen the exact same way as well? For example, suppose a particular quantum event has a 25% probability of occurring, and thus would have that 25% probability in duplicate particle in the duplicate universe. If the event occurs in the first universe, then does it necessarily occur in the second universe too? This can be expanded to ask simply: suppose there were a perfectly fair coin flipped by a perfect flipper. Would it always flip the same way in both universes?

The question is: would truly random events be duplicated as well?

We don't know. This question just goes back to the question of the interpretation of quantum mechanics. Some interpretations include probability fundamentally and some of them don't. None of us on this board are gonna settle the issue by discussing here

the answer is $P=e^(x*t)/e^(x*T)$ , where t is when you are measuring and T is the amount of time you have. Statistically, P is probably not going to be bigger than 100 percent anytime, so the chance of success is always bigger than zero percent but less than 100 percent.

excuse me, the correct answer is:

$P=e^{-xt}/e^{-xT}$

And the real answer is that if T is bigger than t, P is always going to be bigger than 1 (which is bigger than 100%). The variable x is the wavefunction.

Therefore to solve for the real probability, take the inverse of P, which is:

$p=1/P$

If you assume a normal distribution, then p will never be less than 0% or will never be greater than 100%.

Not so fast.
Let's say for example that I had a wavefunction be $x=-sin(t)$ .
Now lets put that into the probability equation.
$P=e^{sin(t)*t}/e^{sin(t)*T}$
This is $P=e^{sin(t)*t-sin(t)*(T)}$
Assuming that you only have 1000 seconds in your Universe (we have many more), and you only want to see the probability of this function after 10 seconds since the creation of your universe...
$P=e^{sin(10)*(10)-sin(10)*(1000)}$
This is... P=2.186x10^-75 (unthinkably small)
However, if we increase the time to say, well 100 seconds after the big bang...
This would be... 1.183*10^-385 (unthinkably smaller than unthinkable)
Now lets increase the time of your universe to say T=1000000 seconds with t=100 seconds.
The new P=1.5732x10^-427654 (practically zero)
The only fact that remains is that by decreasing the length of time of your universe and decreasing the time of when the wavefunction happens increases the probability that said wavefunction will exist. However, we see things because time is relative and has no real properties. Everything is happening at once in the big picture of things since physics has a good way of capping the limit of energy expansion.
