If (\binom{n}{1}=14), what is the value of (n)?

Answer and explanation

Correct answer: 14

The number of ways to choose one object from \(n\) objects is \(\binom{n}{1}=n\), since each of the \(n\) objects can be chosen separately. Hence, \(\binom{n}{1}=14\) gives \(n=14\). Option 13 is incorrect because \(\binom{13}{1}=13\). Exam tip: Remember the basic results \(\binom{n}{1}=n\) and \(\binom{n}{n}=1\).
