Probability over different time spans

Question

I have aquestion: Which is more likely to happen: flipping a coin 10 times in a 10 minute period and getting heads each time OR flipping a coin 10 times but over a period of 10 years and getting heads each time? The flipping itself takes the same amount of time. But it is the interval between flips that differed between scenarios.
I am not in math. I have some knowledge of bio-statistics. Thank you!

Answer 1

Assuming the coin is unaffected by the passage of time, both events have probability $2^{-10} \approx 0.001$.

The above also assumes that the coin is fair: the probability of heads is the same as that of tails. If the probability of flipping heads was instead $p$, we would have $p^{10}$ for both events instead.

Answer 2

The time is not important to determine the probability of this kind of events, thus the two events are equally likely.

Answer 3

They are equally likely, because part of the mathematical definition of "fair coin" is that it has no memory of how it came up the last time it was flipped. A similar question in bio-statistics (which you know) may well have a very different answer. Biological systems age.
