Question

If A, B are disjoint sets then n(A) + n(B) – n(A∪B) = ____

Answer 1

Answer:

0

Step-by-step explanation:

Since A and B are disjoint sets therefore n(AUB) = n(A) + n(B) this implies,

n(A) + n(B) - n(AUB) =0

Answer 2

• zero(0)

Step-by-step explanation:

As the two set A and B are two disjoint set,

Then,

n(A)+n(B)=n(AuB)

A.T.Q

• n(A)+n(B)-n(AuB)
• n(AuB)-n(AuB)
• 0
