#### Answer

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.
