Question 1 of 8

No calculator

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

S = \{1,\,3,\,5,\,7,\,9,\,11,\,13,\,15\}

Event \(A\) is empty: \(A = \varnothing\). It contains no outcomes

(a)1 mark

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

An outcome is one result; the sample space \(S\) omits the possible outcome \(15\); and \(A\) is the specified event

The experiment produces one result. An outcome is \(1\); \(S\) contains every possible outcome; and \(A\) is the empty event, containing no outcomes

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

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