<s>[INST] Here is a list of the names of 20 students who took a test, one of whom will be randomly awarded a prize:

Aberto, Alaric, Alex, Andrew, Bella, Ben, Braxton, Brianna, Bryce, Carlos, Chloe, Emily, Ethan, Isabel, Liam, Lucas, Madison, Matthew, Mia, Seth

Assuming the randomly selected name is equally likely to be any of the 20 students, what is the probability that the prize will be awarded to a student with a name that does not start with a vowel?[/INST]
