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. A. 10.00% B. 15.35% C. 17.82% D. 18.20% E. 20.00%

B?

OpenStudy (dangerousjesse):

First, can you tell me the number of e's and the total number of letters?

OpenStudy (anonymous):

18 E's

OpenStudy (dangerousjesse):

And the rest, including the e's?

OpenStudy (mathmale):

all right. 18 e's, out of how many letters total (not including spaces, etc.)?

OpenStudy (anonymous):

101?

@DangerousJesse @mathmale

OpenStudy (dangerousjesse):

Sorry, had to run it through Python. 101 is correct :)

OpenStudy (dangerousjesse):

Solve\18\div101\]Then move the decimal over two spaces to the right.

OpenStudy (dangerousjesse):

-_- \[\large\18\div101\]

OpenStudy (dangerousjesse):

Not fixing it.

OpenStudy (anonymous):

17.82?

OpenStudy (dangerousjesse):

Yep :)

OpenStudy (mathmale):

If you have 18 letter e's out of 100 letters total, then the prob. of drawing an 'e' is just 18/101. You could leave this answer as is or find the decimal fraction equivalent.

OpenStudy (dangerousjesse):

Yeah, the question is asking for the percentage :)
