Задание

Даны множества \(\displaystyle A=\{3;\,5;\,7;\,9;\,11 \}\) и \(\displaystyle B=\{3;\,6;\,9;\,12 \} \small.\)

Найдите множество \(\displaystyle A \cup B\small.\)

\(\displaystyle A \cup B=\{3;\,6;\,9;\,12\}\)
\(\displaystyle A \cup B=\{3;\,5;\,7;\,9;\,11\}\)
\(\displaystyle A \cup B=\varnothing\)
\(\displaystyle A \cup B=\{3;\,9 \}\)
\(\displaystyle A \cup B=\{3;\,5;\,6;\,7;\,9;\,11; \,12 \}\)
