Answer:
0.10 or 10%
Step-by-step explanation:
Since each student must take at least 2 courses, if no student took all three courses, the sum of the percentages would total 200% (counting each student twice). Therefore, the proportion of students taking all three courses is the difference between the sum of all percentages and 200%:
0.10 or 10% of the students take all 3 courses.
