Hello soccerchic96If the odds are $\displaystyle m:n$ in favour of an event, then the probability that the event will occur is $\displaystyle \frac{m}{m+n}$. For example, if the odds are 2 to 1 in favour of an event, then the probability that it occurs is $\displaystyle \frac{2}{3}$, and the probability that it doesn't is $\displaystyle \frac{1}{3}$.
