6 students have not been to Germany, Spain, or France
How to determine how many students have not been to Germany, Spain, or France?
Given that 19 students have been to Spain,
Only Spain visit = 19 - 3 + 3 + 6
Only Spain visit = 19 - 12 = 7
Students that have not been to Germany, Spain, or France = Total students - ( 7 + 3 + 3 + 6 + 5 + 4 + 4 )
Students that have not been to Germany, Spain, or France = 38 - 32 = 6
Therefore, only 6 students have not been to Germany, Spain, or France
