Question

Answer 1

Answer:

please mark me as brainleist answers and please follow

Step-by-step explanation:

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. In Figure 1.4, the union of sets A and B is shown by the shaded area in the Venn diagram.

Answer 2

Answer:

In union of any sets, you have to simply combine all the members of both the sets. Eg:

A={1,2}

B={3,2}

AuB={1,2,3}

In intersection, you have to include only common members of both the sets. Eg:

A intersection B={3}
