<font face="Times New Roman" size="+2">


If the probability of a success is *[tex \Large \frac{a}{n}] and the probability of failure is *[tex \Large \frac{b}{n}] where *[tex \Large a\ +\ b\ =\ n], then the odds in favor of a successful outcome is *[tex \Large a\,:\,b]


Your *[tex \Large a] is 5 and your *[tex \Large n] is 13.  You can figure out the rest.
