** These numbers might or might not be completely accurate, but the calculation of the relative frequencies as percents follows from the tallies:

91-95 1 1/50 = 2%

96-100 3 3/50 = 6%

101-105 5 5/50 = 10%

106-110 7 7/50 = 14%

I did not enter my answers in percentage form, I left them in decimal form but I got the answers right.

query problem 13.1.35 empirical probability distribution for letters of alphabet

......!!!!!!!!...................................

RESPONSE -->

A - .08/.385 = .21=21%

E - .13/.385 = .34=34%

I - .065/.385 =.17=14%

O - .08/.385 = .21=21%

U - .03/.385 =.08=8%

A bar graph would probably be the best way to display the results.

.................................................

......!!!!!!!!...................................

09:09:28

** The probabilities for A, E, I, O, U are:

.08. .13, .065, .08, .03.

The sum of these probabilities is .385

The probabilities of the letters given a vowel:

.08 / .385 = .208

.13 / .385 = .338

.065 / .385 = .169

.08 / .385 = .208

.03 / .385 = .078

These probabilities total 1. **

......!!!!!!!!...................................

RESPONSE -->

I gave the percentage this time and I figured a bar graph would best illustrate the outcome

.................................................

Very good.
