Question

You roll a number cube. What are the odds that you will roll an even number?

Answer 1

`1:1`.

Explanation:

Probability = `"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: `3/6= 1/2`

Odds = `"number of desirable outcomes"/"number of non-desirable outcomes"`, often written as `a:b` instead of `a/b`.

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