due to gambler's fallacy the probability of it landing heads is still 50/50 so

So you'd have to try x times?

Gambler's fallacy is something entirely different.

My answer
>>14180037
He didn't specify how many times the coins are flipped so I assumed n = number of trials = infinite at which point the chance of flipping at least a 100 heads converges to 100 %. But because n isn't defined, the question isn't actually answerable.

More like 80,393,873,682,600 billions years.

So if all humans tried to do it now, what's the chance some succeed?

What if on the flip following 99 consecutive outcomes as heads, Monty Hall appears and shows you a second coin that is tails. How does that change your odds of your next flip being heads?
