there is 21/7 graders who want to play an instrument other than drums. There was 63 students in all based on the results Xpress, the probability that a seventh grader chosen at random, who played instrument other than drums as a percent to the nearest whole number

Answer 1

The probability that a seventh grader chosen at random plays an instrument other than drums is (21/63) = 1/3.

To convert this into a percentage, we multiply by 100:
(1/3) * 100 = 33.33%

Therefore, the probability that a seventh grader chosen at random plays an instrument other than drums as a percentage to the nearest whole number is 33%.
