Answer

Explanation:

Step1: Count total letters

Count the number of non - space and non - punctuation letters in the text. "In English, the letter e appears most frequently among alphabetical characters. In these lines, it appears eighteen times." After excluding spaces and punctuation, the total number of letters is 118.

Step2: Calculate probability

The experimental probability $P$ of an event is given by the formula $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. Here, the number of favorable outcomes (number of 'e's) is 18, and the total number of outcomes (total non - space and non - punctuation letters) is 118. So $P=\frac{18}{118}\approx 0.1525$.

Step3: Convert to percentage

To convert the decimal to a percentage, multiply by 100. $0.1525\times100 = 15.25%$, which is closest to 15.35%.

Answer:

B. 15.35%
