Question

For \[E=\{3,6\}\] and \[F=\{2,4,6\}\], what is \[E\cap F\]?

Options

• \[E\cap F=\{3,6\}\]

• \[E\cap F=\{2,4,6\}\]

• \[E\cap F=\{6\}\]

• \[E\cap F=\{2,3,4,6\}\]

Answer 1

The common outcomes of E and F must be both multiples of 3 and even. Only 6 has both properties, so \[E\cap F=\{6\}\].
