$1 : 1$ $1:1$ .

Explanation:

Probability = $\frac{number of desirable outcomes}{total number of possible outcomes}$ $"number of desirable outcomes"/"total number of possible outcomes"$

On a die, (number cube), there are 6 numbers, 3 of them are even
,
the probability of throwing an even number: $\frac{3}{6} = \frac{1}{2}$ $3/6= 1/2$

Odds = $\frac{number of desirable outcomes}{number of non-desirable outcomes}$ $"number of desirable outcomes"/"number of non-desirable outcomes"$ , often written as $a : b$ $a:b$ instead of $\frac{a}{b}$ $a/b$ .

So the odds of rolling an even number are $3 : (6 - 3) = 1 : 1$ $3:(6-3)=1:1$ .
