A fair number cube with the numbers $1$, $2$, $3$, $4$, $5$, and $6$ is rolled.

1. What is the probability of getting an even number?

   Hint (a):

   How many even numbers are there on the cube? How many possibilities are there for what can be rolled?

   Answer (a):

   There are $3$ even numbers ($2$, $4$, $6$) and $6$ possibilities, so the probability of rolling an even number is $\frac{3}{6}$ or $\frac{1}{2}$.

2. What is the probability of getting a factor of $6$?

   Hint (b):

   Follow the same steps as outlined in part (a).

   More Help (b):

   $1$, $2$, $3$, and $6$ are all factors of six.
