The correct answer is because it is not 50-50.
That is just a myth that people believe and that is the perception of human nature.
If you want to win 100% of your bets...bet when the odds are a 100% in your favor...if you want to win 80% of your bets...bet only when the odds are 80% in your favor...
99.99999% of the gamblers make bets over 50% of the time that they have only a 35 to 40% chance of winning or less.
now i know 99% of you will not comprehend this...but this is the correct answer to this question.
So using this formula plus the second part that goes with it...i can easily pick out winners...
but i dont gamble...but if some one was to pay me i would consider picking out winners for them...
