Remember these definitions:

Theoretical Probability: This is what is expected to happen.

Experimental Probability: This is what actually happened in an experiment.

(A) - Since a number cube has $$6$$ even sides, the theoretical probability of rolling a side ($$3$$ in this case,) is $$\frac{1}{6}$$.

(B) - If the number $$3$$ came up $$67$$ times out of the $$450$$ times rolled, then the experimental probability is $$\frac{67}{450}$$.
