Work Step by Step

16% of the students chose astronomy. 22% of the students chose oceanography. To find the percentage of students that chose either astronomy or oceanography, we simply add these two percents. 16%+22%=38%. To find the percentage that did not take biology or oceanography, we must subtract this percentage from the whole, which is 100%. 100%-38%=62%.
