In a "Probability and Statistics for CS" class with 160 students enrolled in it, by the time of the final exam, 60% of the students have mastered discrete probabilities, 75% have mastered continuous probabilities, and 50% have mastered both. For a student to pass the class with at least a C, the student must be able to use at least one type of probabilities. How many students passed the class? (Probability Theory)
