How many four-character license plates consist of a consonant, followed by a vowel, followed by a consonant, and then a vowel? (For this problem, consider Y a vowel.)

6 vowels    20 consonants

 

Assuming we can  have repeats of vowels / consonants

 

(20) * (6) * (20) * (6)  = 

 

120 *  120  = 

 

14400  plates
