Odds. Another way of expressing probabilities is by the use of odds. Suppose I roll a single die and call getting a 4 a favorable outcome. The probability of this happening is of course 1/6, which means that we expect to see a 4 once out of every six rolls. But this can also be expressed in terms of odds. Here's how it works: There are six possible outcomes; one of these is favorable (getting a 4) and five are unfavorable. One then says that the odds against getting a 4 are 5 to 1. This could also be expressed by saying the odds in favor of getting a 4 are 1 to 5.
In general, if we list all the possible equally likely outcomes, the odds in favor of a favorable outcome are expressed as the number of favorable outcomes to the number of unfavorable outcomes. To find the odds against it, we reverse the order of these two numbers.
