what is the formula for n(AUBUCUD) /

Hi!
 
The formula of n (A U B U C U D) is given as:
n (A U B U C U D) = n (A) + n (B) + n (C) + n (D) – n (A ∩  B) – n (A ∩  C) – n (AD) – n (B ∩  C) – n (B ∩  D) – n (C ∩  D) + n (A ∩  BC) + n (ABD) + n (A ∩  C ∩  D) + n (B ∩  C ∩  D) – n (A ∩  B  ∩  C ∩  D)
 
Cheers!

 n((A U B) U (C U D)) = n(A) + n(B) + n(C) + n(D) - n((A n B) U (A n C) U (A n D) U (B n C) U (B n D) U (C n D)).
