Odds and Probability

Identifying the odds of something happening is a little different that calculating the probability. It is written as a ratio; however, it is not written as a fraction.

Odds

The odds in favor of an event is the ratio of the number of ways the outcome can occur to the number of ways the outcome cannot occur.

# of ways the event CAN occur : # of ways the event CANNOT occur.

This is actually a lot easier than probability. So, let's take a look at an example.


Example 1

odds and probability

Odds and probability is pretty easy! Just remember to use a colon instead of a fraction. Also, remember that you are comparing the number of ways the outcome can occur to the number of ways the outcome cannot occur (not the total outcomes).
