Question

a number cube was rolled as part of an experiment. the results are displayed in the table below.

number	1	2	3	4	5	6
frequency	4	6	5	7	3	5

what is the best explanation of how to find the experimental probability of rolling a 3?
to find the experimental probability of rolling a three, write a ratio of the number of times three occurs to the total number of trials. simplify if necessary.
to find the experimental probability of rolling a three, write a ratio of the total number of trials to the frequency of the number three. simplify if necessary.

Explanation:

Experimental probability is calculated as the ratio of the number of times an event occurs to the total number of trials. For rolling a 3 on the number - cube, the event is rolling a 3 and the number of times it occurs is its frequency. The total number of trials is the sum of all frequencies.

Answer:

To find the experimental probability of rolling a three, write a ratio of the number of times three occurs to the total number of trials. Simplify if necessary.
