# Odds vs. Probability: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Published on February 1, 2024
Odds compare the likelihood of an event happening to it not happening, while probability measures the likelihood of an event occurring out of all possible outcomes.

## Key Differences

Odds are a ratio that compares the likelihood of an event occurring to it not occurring. Probability, on the other hand, is a measure expressed as a fraction or a percentage that indicates the likelihood of an event occurring out of all possible outcomes.

In betting, odds are often used to show the potential winnings relative to the stake. Probability is used more broadly in various fields, like statistics and mathematics, to quantify the uncertainty of an event.

To calculate odds, you divide the number of favorable outcomes by the number of unfavorable outcomes. Probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Odds can be greater than 1, which happens when an event is more likely to occur than not. Probability is always a number between 0 and 1, where 1 indicates certainty and 0 indicates impossibility.

Odds provide a direct measure of the likelihood of an event in comparison to its non-occurrence, while probability gives a more holistic view of the event's occurrence in the context of all possible outcomes.
