My two cents ...

The probability that Ann wins is 505/1296.
The probability that Ann loses is 791/1296.

The odds on Ann winning are 505 to 791.
The odds on Ann losing are 791 to 505.

Hence if you want to make a bet on Ann to win, the other party
should offer fair odds of 791 to 505 (so you win 791 if you
win, and lose 505 if you lose).
