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 \(\frac{67}{450}\).
