n\left( {A \cap B} \right) = 5,\;n\left( {A \cap C} \right) = 7

and

n\left( {A \cap B \cap C} \right) = 3,

then the minimum possible value of

n\left( {B \cap C} \right)

View answer and explanation

Correct option: C

Option C (3) is correct because the minimum possible value of

n(B \cap C)

is equal to

n(A \cap B \cap C)

when

A \cap B \cap C

is the entire intersection of B and C.
