% of students who
failed the first exam = 100 - 71 = 29
failed the second exam = 100 - 72 = 28
failed the third exam = 100 - 56 = 44
Fraction of the students who failed all three exams
= (0.29) (0.28) (0.44) = 0.035728
% of students who failed all three exams = 3.5728
% of students who passes at least one exam
= 100 - 3.5728 = 96.4272%
