Question

Find the experimental probability of getting the letter e when a letter is drawn at random from this text: In English, the letter e appears most frequently among alphabetical characters. In these lines, it appears eighteen times. Note: Exclude spaces and punctuation marks from your analysis. 10.00% 15.35% 17.82% 18.20% 20.00%

Answer 1

the correct answer is C. 17.82%

Answer 2

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 :-

$\text{P(e)}=\frac{\text{Number of times letter e appear}}{\text{Total letters}}\\\\\Rightarrow\text{P(e)}=\frac{18}{101}$

In percent, $\text{P(e)}=\frac{18}{101}\times100=17.8217821782\approx17.82\%$

Hence, the the experimental probability of getting the letter e when a letter is drawn at random the given text is  17.82%
