Question

if A,B are disjoint sets then n( A intersection B)​

Answer 1

Answer:

Step-by-step explanation:

Two sets are said to be disjoint if they have no element in common. Equivalently, disjoint sets are sets whose intersection is the empty set. ... The number of elements in the union (A∪B) is simply the sum of the number of elements in A and the number of elements in B: |A ∪ B| = |A| + |B|

Answer 2

Since A and B are disjoint sets ,

AnB={}, no elements ,so n(A n B) =0
