Just a bit of math
What is Odd?
Odds are used to describe the chance of an event occurring. The odds are the ratios that compare the number of ways the event can occur with the number of ways the event cannot occurr.
$$ Odds = \frac{p}{1 - p} $$For example, if the probability of rain is 0.75 (or 75%), the probability of no rain is 0.25 (or 25%). The odds of rain are 0.75 / 0.25 = 3. This means it’s three times more likely to rain than not to rain.
Important: Odds are not probabilities
