Question

A class rolled number cubes. The results are shown in the table. What is the experimental probability of rolling the number five? Round your answer to the nearest tenth.

Answer 1

17.5%

Explanation:

First you have to find how many times the number cube was rolled. To do that you add up all of the occurrences and get 42+44+45+44+47+46=268.

After finding the total amount of times the cube was rolled, you must find how many times the outcome you are looking for occurred, which in this case is 47 as 5 was rolled 47 times.

Now all you have to do is divide 47/268 and that will get you your answer as probability is expressed as how many times a specific outcome is observed (rolling a 5) over how many times you roll the dice. At the end you can simply multiply by 100 to turn it from decimal form to percent form.
