Given: The different types of shoes worn and their percentage
To Determine: The probability that sandals will be the favourites
Solution
Let us calculate the total percentage
[tex]\begin{gathered} sneaker=54\% \\ boot=16\% \\ sandal=20\% \\ other=10\% \\ Total=100\% \end{gathered}[/tex]
Please note that the probability of an event A from a total occurence of S is calculated as
[tex]\begin{gathered} P(A)=\frac{n(A)}{n(S)} \\ P(A)=Probability\text{ of A} \\ n(A)=number\text{ of A} \\ n(S)=Total\text{ number of all occurence} \end{gathered}[/tex]
Therefore, the probability of favourites been sandal would be
[tex]P(sandal)=\frac{20\%}{100\%}=\frac{1}{5}[/tex]
Hence, the probability is 1/5
