The probability = outcome/total outcomes
The total of the outcomes is the total number of the letters of the given word, then
The total outcomes = 11
The outcome is the number of letter "s" in the word
The outcome = 4, then
The probability of "s" is
[tex]P(s)=\frac{4}{11}[/tex]To change it to percent multiply it by 100% and round it to the nearest 1 decimal place
[tex]\begin{gathered} P(s)=\frac{4}{11}\times100 \\ P(s)=36.4 \end{gathered}[/tex]The answer is 36.4%
