Question

this table shows the favorite pets of 20 students. find the relative frequency of students who chose \dog\.

Explanation:

Step1: Recall the formula for relative frequency

Relative frequency \(=\frac{\text{Frequency of the category}}{\text{Total frequency}}\times100\%\)

Step2: Substitute the values

Here, frequency of "Dog" is \(8\) and total frequency is \(20\). So relative frequency \(=\frac{8}{20}\times 100\%\)

Step3: Simplify the fraction

\(\frac{8}{20}=\frac{2}{5}\), and \(\frac{2}{5}\times100\% = 40\%\)

Answer:

\(40\)
