If you do not succeed, you did not attend lecture or did not study.
Work Step by Step
If you attend lecture and study, you succeed. Let p, q, and r represent the following simple statements: p: You attend lecture. q: You study. r: You succeed. The given conditional statement can be represented in symbolic form as: (p ᴧ q) → r An equivalent statement is the contrapositive: ~r→ ~(p ᴧ q) Using De-morgan's law, we can write: ~r → (~p v ~q) If you do not succeed, you did not attend lecture or did not study.
