Image from store Odds to Probability Text Changer
Description from store This extension looks for American odds (such as "+140" or "-350") on the page, calculates the implied probability, and displays it as a percentage. For example, "+140" becomes "+140 (41.7%)" Assuming the odds are "fair", the implied probability is the percentage chance that the bet is supposed to win. Because sportsbooks charge a fee or "vig" for placing bets, this number will appear slightly higher than the actual probability. This implied probability is simpler way to look at sports betting: a "good bet" is one where you believe the percentage chance is higher than the implied probability.
