Find the probability of rolling a 1 or a 5 with 5,4,3,2,1, die.

I'm just confused by the question and what its' asking and how to solve please help!

I don't know if its saying 1 and 5 like two numbers which probablity would be 2/5 or 40%. Or if it's saying either one or 5 so one of the numbers which would be 1/5 or 20%. Please HELPP! I GET THE CONCEPT JUST NOT IF THEY ARE COUNTING 1 and 5, or just 1 or 5? THANKS !!!
