Answer 1

The number of students not taking any foreign language = 6

P (F U S) = 24

Explanation:

The total number of students in the class = 30

The number of students studying French (A) = 19

The number of students studying Spanish (B) = 12

The students studying both languages (A ∩ B) = 7

Students studying at least one of the language (A U B) = 19 + 12 - 7

= 24

Students taking neither of the foreign language = 30 - 24 = 6
