The odds *[tex \Large m:n] against an event means that the event will not occur *[tex \Large m] times for every *[tex \Large n] times that it does occur.


Hence the probability that the event will occur is:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{n}{m\ +\ n}]


And the probability that the event will NOT occur is:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{m}{m\ +\ n}]

*[tex \LARGE e^{i\pi} + 1 = 0]
My calculator said it, I believe it, that settles it
