Based on these results, express the probability that an eighth grader chosen at
random will play an instrument other than bass as a fraction in simplest form.

Answer 1

35/48

Explanation:

You just want to focus on the 8th graders. Add add the total number of students together to get your denominator. Then just put what your # of bass students are and that is your probability in fraction form. ( the fraction can't be simplified smaller than it already is.)
