Question

For one die, which option correctly describes the Impossible event “Number 7”?

Options

• It contains all outcomes except 6, with \(n = 5\)

• It contains exactly one outcome, \(A = \{7\}\), with \(n = 1\)

• It contains no outcome, \(A = \{\} = \phi\), with \(n = 0\)

• It contains every outcome, \(A = S\), with \(n = 6\)

Answer 1

A die cannot show 7 because its sample space contains only 1 through 6. Therefore, the event contains no outcome and \(n = 0\).
