43 students are taking science ONLY. 95-52=43 21 students are taking math ONLY. 73-52=21 52 students are taking both math AND science. 31 students taking neither. 147-43-21-52=31 Probability of students taking math, science, or both out of the 147 students. P(taking math or science or both)= (43+21+52)/(147) (116)/(147) Result: 78.9%
