In a class of 50 students 30 offer econs 17 offer government and 7 offer neither both. How many students offer both subjects?in a class of 50 student ​

Sagot :

Answer:

4 students take both Economics and Government.

Step-by-step explanation:

Total number of students in the class: 50

Students who offer Economics: 30

Students who offer Government: 17

Students who offer neither Economics nor Government: 7

find out how many students offer at least one of the subjects (Economics or Government). subtract the number of students who offer neither subject from the total number of students:   50 - 7 = 43

Students taking at least one subject = (Students taking Economics) + (Students taking Government) - (Students taking both)

43 (at least one) = 30 (Economics) + 17 (Government) - Both

43 = 47 - Both

Both = 47 - 43

Both = 4
