Question

Min {n(A U B)} = -------​

Answer 1

Answer:

Set A has 7 elements & set B has 8 elements.

Minimum A∪B elements condition: Out of 8 elements of set B, 7 elements are identical to that of set A. In this case A∪B=B & it will have 8 elements.

Maximum A∪B elements condition: A & B are disjoint sets, that no element will be common to them. Then:

n(A∪B)=n(A)+n(B).

A∪B has 15 elements.

Answer 2

Step-by-step explanation:

min {n(A U B)} = max {p,q}

where n(A) = p,

           n(B) = q
