# Betting Odds

Odds are a ratio that measure the likelihood of an event occurring. They are often used in gambling and statistics. Odds can be presented in different formats, such as American, fractional and decimal. Regardless of the format, odds are calculated in the same way. Understanding how to read and calculate betting odds is an important step towards making wise wagers.

A common misconception is that odds are the same as probability. This is incorrect, as odds represent a probability that an event will occur and not the probability that it won’t happen. Probability is a number that indicates the chance of an event occurring, while odds are a representation of that probability divided by the total number of possible outcomes.

Whether you’re betting on sports or games, there’s no doubt that weighing the odds of winning and losing is a crucial part of the process. While calculating and reading odds may seem like a complicated task, it’s actually quite simple once you know the basics.

Odds can be displayed in several different ways, depending on the region and sport. In the United States, for example, odds are shown with plus (+) or minus (-) signs in front of a number greater than 100. The most important thing to understand is that these signs indicate whether the bet is a favorite or underdog, which will affect how much money you can win or lose. Plus and minus odds can also be grouped into two categories: “overs” and “unders”. A bet on an over will have positive (+) odds, while a bet on an under will have negative (-) odds.
