Answer 1

ANSWER :

C. bird = 0.15

cat = 0.25

dog = 0.55

snake = 0.05

EXPLANATION :

From the problem, we have the following frequencies :

bird = 3

cat = 5

dog = 11

snake = 1

The total number of animals is 3 + 5 + 11 + 1 = 20

The relative frequency formula is :

$\text{ Relative Frequency}=\frac{\text{ Frequency \lparen Number per animal\rparen}}{\text{ Total number of Frequency \lparen Total number of animals\rparen}}$

That will be :

$\begin{gathered} \text{ Bird}=\frac{3}{20}=0.15 \\ \\ \text{ Cat}=\frac{5}{20}=0.25 \\ \\ \text{ Dog}=\frac{11}{20}=0.55 \\ \\ \text{ Snake}=\frac{1}{20}=0.05 \end{gathered}$
