How are your grades? In a recent semester at a local university, 600 students enrolled in both Statistics I and Psychology I. Of these students, 87 got an A in statistics, 75 got an A in psychology, and 32 got an A in both statistics and psychology. Round the answers to four decimal places, as needed.
