A finite experiment produces exactly one outcome from the following sample space

S = \{1,\,2,\,3,\,4,\,5,\,6\}

Event \(A\) consists of the outcomes \(\{4\}\)

(a)1 mark

Which statement correctly describes the experiment, one outcome, the sample space \(S\) and event \(A\)?

The experiment is the single result \(1\); \(S\) is that result; and \(A\) is the full list of outcomes

The experiment produces one result. An outcome is \(1\); \(S\) contains every possible outcome; and \(A\) is the specified subset of \(S\)

An outcome is the whole sample space \(S\); \(S\) is the process; and \(A\) is only the one result \(1\)

An outcome is one result; the sample space \(S\) omits the possible outcome \(6\); and \(A\) is the specified event
