A 6 loosing streak is highly possible possible in a 50% game.
6 coin tosses have a 2^6 different outcomes.
2^6=64!!!
There are 64 different outcomes!
If you get 6 losses in a row you get 1 of the 64.
Classic theory of Probabilities and combinatorics.
P(6_loss_streak)= 1/64 = 0,015625 = 1,5625%
This is like loosing a 100-1,5625= 98,4375% win chance game.
You were either unlucky or you made an a LOT of bets.
That's all.
Now calm down and think again about gabling next time!
people dont understand the idea of any number of "red" hits being a possibility, they simply write it off as impossible because they dont want to believe they just lost all their coin, or something. maybe theyre just stupid.
