In a class of 30 students, 20 take mathematics, 17 take physics and 2
take none of the two subjects. How many students take both
subjects?​

Sagot :

Since 2 don’t take either of the classes you can minus them out of the total giving us 28 students and then 20+17 is 37 that mean 9 of them take both
