You're now confusing yourself. Probabilities are a totally different thing to odds. Odds are made up of previous outcomes. Probabilities are totally different. Tell me this. If I tossed 10 coins and they all landed on heads. What would you bet came up next? Surely a tails is the more likely to come up? But say for instance I tossed those coins heads came up ten time but a new person came in. That person never seen my first 10 tosses. For him he sees odds of the coin being heads or tails as 50/50.
