Question

Dana surveyed students in her class. She found that 8 earned an A, 6 earned a B, 4 earned a

C, and 2 earned a D on the last science test. If she randomly surveys one more student from
the class, what is the experimental probability that the student would have earned an A on
the test?

Answer 1

0.4

Explanation:

Given:

Dana found that 8 students earned an A, 6 students earned a B, 4 students earned a C, and 2 students earned a D on the last science test.

To find:

the experimental probability that the student would have earned an A in the test

Solution:

Probability refers to the chances of occurrence of some event.

Number of students who earned an A in the test = 8

Total number of students = 8 + 6 + 4 + 2 = 20

The experimental probability that the student would have earned an A in the test = Number of students who earned an A in the test / Total number of students =
`(8)/(20)=(2)/(5)=0.4`
