$5/3$

Odds is the ratio of favourable outcomes to non-favourable outcomes:

If P is the probability of an event occurring, then:

$1-Pcolor(white)(*)$ is the probability of the event not occurring.

The odds will then be:

$P/(1-P)=> (5/8)/(1-(5/8))= (5/8)/(3/8)= 5/3$

To make this clearer:

The probability of throwing a 6 with a standard die is $1/6$

The odds of throwing a 6 are $1/5$

$P/(1-P)=(1/6)/(1-(1/6))= (1/6)/(5/6)= 1/5$
