Answers
Answer:
40 students failed only in chemistry. So the answer is 40 students.
Answer:
10 students passed both
Step-by-step explanation:
Total number of students = 150
Total number of students that passed math = 50
Total number of student that failed chemistry = 40
Total number of students that failed both = 20
Find the number of students that failed at least 1 subject:
Number of students that failed math = 150 - 50 = 100
Number of students that failed chemistry = 40
Number of students that failed both = 20
Number of students that failed 1 subject = 100 + 40 - 20 = 120
Find the number of students that passed both:
Total number of students = 150
Number of students that failed 1 subject = 120
Total number of students that failed both = 20
Total number of students that passed both = 150 - 120 - 20 = 10
Answer: 10 students passed both.
