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 or 2/5

Explanation:

Dana surveyed 20 students in total and out of those 20 only 8 got an A

so:

`(8)/(20)` now if you simplify it
`(4)/(10)` and if you simplify it again:

`(2)/(5)` or 0.4 in decimal
