Odds of +150 means that for every $100 you bet can win $150 in profit if you win. So if you place $10 bet at +150 odds you will earn $15 in profit plus your original stake back. Odds with a plus sign (+) indicate the selection is an underdog, meaning it has a lower chance of winning but it offers a higher potential payout. The implied probablity is 40%, estimated chance of that outcome happening.
