G(x)-f(x)=10x+2- (-8x+5)
             =10x+2+8x-5
             =18x-3
        
             
        
        
        
Answer:
No, because the probabilities of drawing a vowel versus a constant are not equally likely.
Step-by-step explanation:
Each number in a random number generator is equally likely.  If she assigns only the number 1 to vowels and only the number 2 to consonants, she will get results showing that they are equally likely.
In reality, 5 of the 26 letters are vowels (not including y).  The teacher should assign numbers 1 through 5 to vowels, and numbers 6 through 26 to consonants.  This will be a fair representation.
