Question

if a and b are disjoint sets then ∩ (A∪B) =​

Answer 1

Answer:

hey

Step-by-step explanation:

By definition of disjoint set we mean that there won’t be any common elements in both the sets. Therefore A intersection B will be null.

∴ n(A∩B)=0

⇒ n(A∪B)=n(A)+n(B)−n(A∩B)

⇒ n(A∪B)=n(A)+n(B)−0

⇒ n(A∪B)=n(A)+n(B)−0

∴ A∪B=A+B
