$A, B, C$ সান্ত সেট হলে $n(A \cup B \cup C) = ?$

Question

Accepted Answer

$n(A) + n(B) + n(C) - n(A \cap B) - n(B \cap C) - n(C \cap A) + n(A \cap B \cap C)$

Answer

$n(A) + n(B) + n(C)$

Answer

$n(A) \cdot n(B) \cdot n(C)$

Answer

$n(A \cap B \cap C)$

A,B,CA, B, CA,B,C সান্ত সেট হলে n(A∪B∪C)=?n(A \cup B \cup C) = ?n(A∪B∪C)=?
