Question

For one die, which option correctly describes the Simple / Elementary event “Getting 4”?

Options

• It contains exactly one outcome, \(A = \{4\}\), with \(n = 1\)

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

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

• It contains two outcomes, \(A = \{4, 5\}\), with \(n = 2\)

Answer 1

The event of getting 4 contains the single outcome \(4\). A Simple / Elementary event has exactly one outcome, so \(n = 1\).
