Probability odds explained
Probability odds or implied probability is, as the name suggests, the underlying implied probability of the outcome occurring. It's not an odds format in the usual sense but implied probability is widely used by professional bettors in valuebetting and arbitrage betting. It can for example be used to compare the bookies priced odds to an estimated true probability derived from other data or a sharp bookie. Worth noting is that calculating the implied probability straight from the bookmaker odds doesn't take the bookmaker edge into account and requires all outcomes for an event to calculate the true underlying implied probability.
