Question

Christian randomly selects students from his grade to rate a math test as easy, moderate, or difficult. Of the students he surveyed, 13 said the test was easy, 11 rated it as moderate, and 3 found it difficult. Assuming that all students took the same test, how many of the 162 total students in Christian’s grade would probably rate the test something other than easy?

Answer 1

14 out of the 27 asked rated it as something other than easy.
162 × 14/27 = 84
The answer is 84 students.
