odds calculation

Odds calculation measures the likelihood of an event happening compared to it not happening. It’s expressed as a ratio or a fraction (e.g., 3:1), where the first number indicates how many times the event is expected to occur for every one time it does not. To calculate odds, divide the probability of the event occurring by the probability of it not occurring. For example, if an event has a 25% chance (probability 0.25), then the odds are 0.25 to 0.75, which simplifies to 1:3. Odds provide a clear way to understand and compare the chances of different outcomes.
