This May Be The Most Counterintuitive Probability Paradox I've Ever Seen | Can you spot the error?
WARNING: If you haven't see this paradox before (and probability isn't your thing), it may seem like math is broken here. I just want to say that it's not and it took me A LOT of thinking to finally see why. I encourage you to watch the video and see what conclusions you come to, but then check out the follow up video (https://youtu.be/ElB350w8iJo), or pinned comment, for more of an explanation about what's going on.
