Answer 2

Answer:

For A = {1, 2}, B = {2, 3}, U = {1, 2, 3, 4}, find the following using a Venn diagram:

\footnotesize{\mathbf{\color{green}{ A \cup B }}}A∪B

is pronounced as: A union B

means: the new set that contains every element from either of A and B; if a thing is in either one of these sets, it's in the new set

in terms of the elements: \small{ \{1, 2\} \cup \{2, 3\} }{1,2}∪{2,3}Venn diagram:A union B is shaded

my answer: \footnotesize{\mathbf{\color{purple}{ A \cup B = \textbf{\{}1, 2, 3\textbf{\}} }}}A∪B={1,2,3}

The Venn diagram above illustrates the set notation and the logic of the answer. Since "union" means "everything in either of the sets", all of each circle is shaded in. (If you're not clear on the logic of the set notation, review set notation before proceeding further.)
