    A clarification: The standard term for what I called a "Strong Nash" is actually "Strict Nash". "Strong Nash" means something else, but it's only relevant in more complicated situations, so I hope it doesn't cause confusion here. But strictly speaking, I should have used "Strict" in this video!

    There is still a problem with that test, in a real world cheaters would probably be way fewer, maybe 1 in 1000 and if the test randomly accuses 5% of the innocents then on 1000 blobs, approximately 50 would be accused but only 1 would be cheating. Meaning the probability that someone who is accused actually cheated would be near 2%...

    This video made me look up whether flipping a coin is actually 50/50 and lo and behold, Bartoš et al. in 2023 proved that there is actually on average a 51% bias towards the side facing upwards before the flip. The crazy part to me is that this was only tested in **2023**. in the two thousand and twenty three years since god made this earth nobody had scientifically inquired into that

    I'd love for you to a video on Binomial distribution but with a twist. Imagine a Basketball player that has a 60% chance of shooting a basket. We know that to find out the chances the player can make 3 out of 10 shots, we will have to apply Binomial theorem. However, what If each numbered shot had a value - say an amount of prize money the player gets and each shot has a different amount - say shot 1 is $500 and shot 2 is $10 and so on. The numbers per se don't matter but that each shot has a different value. Now how do you find a mathematical formula that can answer the probability that the player will make a sum of money between $a and $b.

    I found a problem with the game, since the cheater to fair ratio is so great, you can infinitely continue playing if you only guess cheater without ever flipping a coin

    What i like most about this is that the various steps of hypothesis testing are not presented as "here's the rules, learn them and apply them" - but rather as a set of designed/engineered choices aimed a a specific goal, and showing what goes wrong when you leave out one of the engineered steps.
