Odds to Probability Text Changer Extension

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.
