Question

3. A class rolled number cubes. Their results are shown in the table. What is the experimental probability of rolling the number 1? Round your answer to the nearest tenth.

17.2%
16.4%
15.7%
17.5%

Answer 1

15.7%

Explanation:

Experimental probability is the probability of something that is determined by doing an experiment.

To find the probability, divide the number of rolling a one and add all the occurrences of every other result.

So,

42 / (42 + 44 + 45 + 44 + 47 + 46) =

42 / 268 =

0.156716 =

15.6716

Rounded to the nearest tenth, the probability of rolling a one would be 15.7%.
