# Answer The Given Question In One Word. Let A And B Be Two Sets Having 4 And 8 Elements Respectively. Write The Minimum Number Of Elements That A∪b Can Have.

n (A∪B) will be minimum when n (A ∩ B) = 0 and maximum when n (A ∩ B) = 4.

n (A ∪ B) = n (A) + n (B) − n (A ∩ B) = (4 + 8 − 4) =8.

The minimum number of elements in A ∪ B = 8.
