    if you get a million people to flip a coin 50 times. Some of them will get all 50 to be heads.

    Flipping a coin 50 times has 1.1 quadrillion possible outcomes, only 2 of which are all heads or all tails. I think you’d need more than a few billion to reliably see those results.

      I think though, you get the point.

      Now here is a bonus question for you. If I give you a coin and ask you to flip it 20 times, and they all come up heads. What are the odds that if you flip it again it will come up heads?

        I think it’s higher than a 50% chance of heads, because you have evidence for it being an unfair coin.

      yeah that’s over a one in a billion chance to get all heads in just a million tries.
