If P = {3, 7, 11, 13} and Q = {2, 4, 8, 16}, which of the following is correct

  • A \((P\cap Q)^l={2, 3, 4, 13}\)
  • B \(n(P\cup Q)=4\)
  • C \(P\cup Q = \emptyset\)
  • D \(P\cap Q = \emptyset\)

The correct answer is D. \(P\cap Q = \emptyset\)

This is because the intersection of two sets, denoted by \(P\cap Q\), is the set of elements that belong to both P and Q.

In this case, there are no elements that are common to both P and Q, so the intersection is the empty set, denoted by \(\emptyset\).
