Randomness looks like white noise. You can&#x27;t distinguish computer randomness (provided that it&#x27;s a proper PRNG) from physical coin flips. Computers don&#x27;t &quot;even out spectrum&quot;. The longer the coin flip run, the less likely it is to happen, e.g. you would need on average 2046 coin throws to get 10 heads in a row.<p>TL;DR probability theory<p>(If you have free time and want to have some fun, throw a coin and draw a picture recording throws. I once generated a password by throwing a coin for more than hundred or times — each bit taking more than 1 throw to avoid biases — <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Fair_coin#Fair_results_from_a_biased_coin" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Fair_coin#Fair_results_from_a_...</a>)
