English has  letters that can be vowels. This includes Y, which can be either a consonant or a vowel; for this problem, we'll consider Y a consonant.  The other  English letters always consonants. How many two-letter "words" can we make from these letters if we are required to use at least one vowel?

Assuming repeats :  Number of possible  "words" with no restrictions =   (26)(26)  = 26^2 =  676

 

Again, assuming repeats......Number of possible words with only  consonants =  (21)(21) =  441

 

Number of words with at least one  vowel  =   676  - 441   =  235
