Remember that, ‘odds’ are the probability on a different scale. Here is the formula: If an event has a probability of p, the odds of that event is p/ (1-p). Odds are the transformation of the probability. Based on this formula, if the probability is 1/2, the ‘odds’ is 1. clamshell pink

The probability of it happening is 1/6. So the odds in favor of us winning are (1/6) / (5/6) = 1/5 or 1:5. Or the odds of us losing are (5/6) / (1/6) = 5:1. The odds are clearly against us winning. downhole slotted tube
