A box has 5 CDs and 10 DVDs. You pick out one disc. What is the chance it is a CD?

Huh

I think you got confused anon

5+10=15

so the chance of it being a CD is 5/15    or    1/3

1/4 or 25%. The reason for that is because there are 5 cd's and 10 dvd's so add them up, and you get 15. and the probabability of it being a cd is 25%
