Question

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

Answer 1

Answer:

0.4

Step-by-step 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 = $\frac{8}{20}=\frac{2}{5}=0.4$
