Loss Streak Probability (per 100 bets)

How it works: Break-even win rate = 1 / decimal odds. This is also the implied probability. To profit long-term, your actual win rate must exceed this. Loss streak probability: the chance of losing N in a row at some point in 100 bets = 1 - (1 - (1-p)^N)^(100-N+1) approximately, where p is win probability.
