Here you go :) . . . . ..
 
        
        
        
6x+4=-11
6x=-15
X=-15/6
X=-2.5
        
             
        
        
        
There are 26 letters in the alphabet, 5 are vowels, therefore, the probability of choosing a vowel the first time is:

and the second time is:

Continuing with this reasoning, we get that the probabilities each time are:

Finally, the probability that you get all vowels is the product of the probabilities:

Writing the above result as a percentage we get:
