Answer: 17.82%
Step-by-step explanation:
From the given line " In English, the letter e appears most frequently among alphabetical characters." there are 101 letters , from the letter e appears 18 times.
Now, the experimental probability of getting the letter e when a letter is drawn at random the given text is given by :-
[tex]\text{P(e)}=\frac{\text{Number of times letter e appear}}{\text{Total letters}}\\\\\Rightarrow\text{P(e)}=\frac{18}{101}[/tex]
In percent, [tex]\text{P(e)}=\frac{18}{101}\times100=17.8217821782\approx17.82\%[/tex]
Hence, the the experimental probability of getting the letter e when a letter is drawn at random the given text is 17.82%
