Answer:
2/15
Explanation:
Experimental probability is the chance of getting the desired outcone out of the maximum possible outcome. In this case, the outcome desired is for rolling 3 which is 20 but the total possible outcome is 150. The theoritical probability would be 1/6 for six sided but the experimental probability is 20/150
When simplified, 20/150=2/15
Therefore, experimental probability is 2/15
