Question

What is the complement of an event \(A\)?

Options

• Every outcome that is in \(A\); written \(A'\)

• All outcomes in both \(A\) and \(S\); written \(A'\)

• No outcome of \(S\); written \(A'\)

• All outcomes of \(S\) not in \(A\); written \(A'\)

Answer 1

The complement includes precisely those sample-space outcomes that the event does not include. It is denoted by \(A'\).
