Answer
(a)
The provided compound statement can be written in simple statements as\[p,q,r\].
Here, \[p,q,r\]represents two simple statements:
\[p:\]I miss class.
\[q:\] They take attendance
\[r:\] There are pop quizzes.
Therefore, the provided compound statement can be written in the symbolic form as:
\[\sim p\leftrightarrow \left( q\vee r \right)\]
(b)
The truth table is as follows:
c)
So, from the truth table it can be stated that when the component of provided compound statement\[\sim p\leftrightarrow \left( q\vee r \right)\] has different truth value, then only resultant statement is false.
Therefore, the statement is true when p is true and q and r are false.
