E=.13

I=.065

O=.08

U=.03

.08+.13+.065+.08+.03=.385

A=.08/.385 .208

Given Solution:

`aThe 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
