91-95 1 1/50=2%

96-100 3 3/50=6%

101-105 5 5/50=10%

106-110 7 7/50=14%

111-115 12 12/50=24%

116-120 9 9/50=18%

121-125 7 7/50=14%

126-130 4 4/50=8%

131-135 2 2/50=4%

this is much easier than probability

`questionNumber 140000

** 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%

111-115 12 12/50 = 24%

116-120 9 9/50 = 18%

121-125 8 8/50 = 16%

126-130 3 3/50 = 6%

131-135 2 2/50 = 4% **

`questionNumber 140000

** 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. **
