If 8/13 is the probability that an event will occur, then 1 - 8/13 = 5/13 is the probabilty that the event won't occur. This means the odds of getting the event are "8 to 5".
Note that "odds" is not the same thing as "probability". Probability is the number of ways an event can occur divided by the total number of possible events. "Odds" is defined as the ratio of the number of ways an event can occur to the ways the event can NOT occur.

Depends on how you want to talk about the odds. If you are betting, you would want to win $13 for an $8 bet so the odds are 13 to 8. If you talking about the percentage "odds" then divide 8 by 13 and get 61.53% odds that it will occur.

The probability is the ratio between the event's likelihood and all possible outcomes. In this case, if you try 13 times, you'll get the specified event 8 times.
The odds are the ratio between the event's likelihood and all *other* outcomes. Subtract 8 from 13 to get the other figure in your odds.
Therefore, the odds are 8:5.

8/13 divided by 5/13 = 8/5
