## Union and Intersection of Sets

Sets \(A\) and \(B\) are both subsets of \(U = \{1, 2, 3, 4, 5, 6, 7, 8, 9, 10\}\) and defined as follows:

\[ A = \{ x \in U : x < 7 \} \]
\[ B = \{ x \in U : x > 3 \} \]

Find \( A \cup B \) and \( A \cap B \). Present your answer by listing the elements of the sets.

\[ A \cup B = \{ \_\_\_\_\_\_\_\_\_\_\_\_ \} \]

\[ A \cap B = \{ \_\_\_\_\_\_\_\_\_\_\_\_ \} \]
