Question 1117436: I don't know if this question would fall into this topic, but can someone help me? I'm self-reviewing for my college entrance exam which is already coming, and I encountered this problem in a book I'm reading.
Use set-builder notation to represent set D = (red, blue, yellow).
My answer was: D = (red, blue, yellow | red is a primary color). Is this one correct or?
Another one from the rule method problem is:
Use the rule method to represent (April, June, November, September).
My answer was: A is the set of months of the year.
Roster method and Rule method are kind of easy to understand for me, but I get quite confused when it comes to set-builder notation. Hoping that you could help me. Thank you in advance! :D

I don't think that in the entrance exam they will give you twisted or over-twisted questions/problems.
