Question

Given the following sets.

A = {0, 1, 2, 3}

B = {a, b, c, d}

C = {0, a, 2, b}

Find B is a union of C
A is an intersection of B

Answer 1

B union C, or \(B \cup C\), is the set of all elements from both sets B and C.
A intersection B, or \(A \cap B\), is the set of all elements common in A and B.

Answer 2

Let's start with an example:
A = {1,2,3,4}
B = {2,4,6,8}

\(A\cup B\) = {1,2,3,4,6,8}
\(A \cap B\) = {2,4

Answer 3

Thank you, I already figured it out though
