Question

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

Answer 1

Find the required probability

On a number cube, there are $6$ numbers, $3$ of them are even and $3$ are odd

As, $\mathrm{odds}=\frac{\mathrm{Number}\mathrm{of}\mathrm{desirable}\mathrm{outcomes}}{\mathrm{Number}\mathrm{of}\mathrm{non}\mathrm{desirable}\mathrm{outcomes}}$

Here, the number of desirable outcomes are $3$ and the number of non-desirable outcomes are $3$.

So, Odds $=\frac{3}{3}$

$\Rightarrow$ Odds $=1:1$

Hence, the odds that you will roll an even number is $1:1$.
