Задание

Даны множества \(\displaystyle A=\{5;\,6;\,7;\,8;\,9 \}\) и \(\displaystyle B=\{3;\,6;\,9;\,12 \} \small.\)

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

\(\displaystyle A \cap B=\{6;\,9 \}\)
\(\displaystyle A \cap B=\{3;\,5;\,6;\,7;\,8;\,9; \,12 \}\)
\(\displaystyle A \cap B=\{3;\,6;\,9;\,12\}\)
\(\displaystyle A \cap B=\{5;\,6;\,7;\,8;\,9\}\)
\(\displaystyle A \cup B=\varnothing\)
