Question

Let A and B are two disjoint sets, given that n(AUB) = 2.

What are the possible values of n(A) and n(B)?​

Answer 1

Answer:

Correct option is

A

n(A∪B)=n(A)+n(B)

A and B are two disjoint sets.

∴ A∩B=ϕ ⟹ n(A∩B)=0

Since, n(A∪B)=n(A)+n(B)−n(A∩B)

=n(A)+n(B)−0=n(A)+n(B)

Hence, n(A∪B)=n(A)+n(B)

Answer 2

Answer:

Step-by-step explanation:

n(A)=1, n(B)=1
