Let A = (0,2,4,6,8,10), B = (0,1,2,3,4,5,6,7) and C=(4,5,6,7,8,9,10,11). Find : (5 pts each) a (AUB) nc b (ANBJUC ci An B nc а С

ANSWER:

A U B U = { 4 , 6 }

Explanation:

A U B = {x : x ∈ A or x ∈ B}.

The union of two sets is a set containing all elements that are in A or in B (possibly both). For example, {1,2}∪{2,3}={1,2,3}. Thus, we can write x∈(A∪B) if and only if (x∈A) or (x∈B). Note that A∪B=B∪A.
