How do you calculate odds of winning betting?

Money Line odds or American odds For example, if the American odds are +200, this means that you would win $200 if you bet $100. For positive odds, the formula is: 100 / (Money line odds + 100). For negative odds, the formula is: Money line odds / (Money line odds + 100).

So our 1 : 2 odds of winning translate to a 33% chance that we'll win.
