1. The number of times (r) that a 3 or 4 appers on a number cube is 2, while the total number of sides (t) on a number cube is 6
r=2, t=6
2. To find the probability of rolling a 3 or 4, simply place the number of desired outcomes (r) above the number of total outcomes (t)
$\frac{r}{t}=\frac{2}{6}=\frac{1}{3}$
