I'm taking Fundamental Discrete Structure and I want to ask a logical question.
Let p be “Erin reads Berita Harian”, let q be “Erin reads Kosmo”, and let r be “Erin reads Metro”.
Erin reads Berita Harian or Kosmo, but not Metro.
May I know how do I write it in symbolic form? I know that the first one will be "p or q" but how do I include the "but not Metro"?
