For the alternative rock band, see Odds . In probability theory and statistics the odds in favour of an event or a proposition are the quantity p / (1 − p) , where p is the probability of the event or proposition. In other words, an event with m to n odds would have probability m/(m + n). For example, if you chose a random day of the week, then the odds that you would choose a Sunday would be 1/6, not 1/7. These 'odds' are actually relative probabilities. Generally, 'odds' are not quoted to the general public in this format because of the natural confusion with the chance of an event occurring being expressed fractionally as a probability. Thus, the probability of choosing Sunday at random from the days of the week is 'one-seventh' (1/7), and although a bookmaker may (for his own purposes) use 'odds' of 'one-sixth' the overwhelming everyday use by most
