INTERSECTION

\(A \cap B\), \(A\) and \(B\), elements which are common to both \(A\) and \(B\).

\(\xi = \{2, 3, 4, 5, 6, 7, 8, 9\}\)

Consider the set \(A = \{5, 6, 7, 8, 9\}\) and \(B = \{2, 3, 4, 5\}\)

  • The element \(5\) is common in both set \(A\) and \(B\).

  • \[\therefore A \cap B = \{5\}\]
