Answer
a) $r\wedge \neg q$
b) $p\wedge q\wedge r$
c) $r\Rightarrow p$
d) $p\wedge \neg q\wedge r$
e) $p\wedge q\rightarrow r$
f) $r\Leftrightarrow (q\lor p)$
Work Step by Step
Because the descriptions for $p, q, r$ are provided, all there is to do is replace the logical concepts with the symbols for logical connectives, as outlined in the text. Looking across each statement is helpful to understand the idea as a whole, and it is also a helpful way to make sure the symbolic notation is equivalent to the words provided.
