10-3 Betting Odds

If you are wondering what 10/3 means in betting, you have come to the right place. Some bookmakers use 100/30, which is equivalent to 10/3 odds in the sports betting markets.

The 10–3 odds of an event happening are the likelihood or probability of that result. 10-3 odds are popular in football betting and for horse racing events in the UK and are a shade shorter than 7-2 odds in the betting market.

In our 10-3 horse racing betting odds guide, we explain what 10 to 3 odds mean, what the 10 to 3 probability is, what the odds payout would be, and why many betting sites use 100/30, not 10/3.
