Have 100 people flip a 2 sided coin. Heads you stay, tails you leave. Continue to flip coins until one person remains. That person will have flipped heads 100% of the time. Are the odds really 50/50?
@ImNotRacistBut, you’ve already forgotten the rules of your own game. Theoretically there can be 2 people left. Then they both flips tails. 25% chance at that point.
