Webn (A) = 4, n (B) = 3 n (A) × n (B) × n (C) = n (A × B × C) 4 × 3 × n (C) = 24 ⇒ n (C) = 24 2 = 2 Web12 aug. 2024 · N(A)=4 n(B)=3 n(A×B×C) = 24 => n (4×3×C) = 24 => n (12×C) = 24 => n(C) = 24/12 = 2 => n(C) = 2 So, now verification : n(A×B×C) = 24 => n (4×3×2) = 24 Hence … WebBut we only want to add it ONCE, not TWICE!!!, So we must subtract the number of elements in A ∩ B ONCE, so it will not be added TWICE, but only ONCE So we subtract it from n(A)+n(B), and we get n(A)+n(B)-n(A ∩ B) and we have this: + + + - And the set A ∩ B that we subtracted away, cancels with the extra A ∩ B, + + + - and we are left with this: + … fodor gyógyszertár
