What is a chance experiment?

• A calculated prediction of an event.

• A repeatable action with unknown outcomes.

• A study of historical events.

• A simulation of a real-world event.

The student council randomly selected 25 students in the school to ask them to choose their favorite chips. The results of the random sample survey are in the table.

Based on the survey, what is the experimental probability that the next student that is surveyed will choose Doritos as their favorite chips?

A number cube with faces labeled from 1 to 6 was rolled 20 times. Each time the number cube was rolled, the number showing on the top face was recorded. The table shows the results. 

                                                           

Based on these results, what is the experimental probability that the next time the number cube is rolled it will land with 5 or 6 showing on the top face? ​ (a)
