First, we need to find the total frequency. This is given by adding all the given frequencies. That is,


\begin{gathered} f_{\text{total}}=4+6+7+5 \\ f_{\text{total}}=22 \end{gathered}

and the relative frequency is the division of the frequency of the corresponding interval by the total frequency,


f_{\text{rel}}=\frac{f_{\text{ interval}}}{f_(total)}

Therefore, the answers are:

a) 4/22 but written in simple form:


(2)/(11)

b)


(5)/(22)
