Let $p, q,$ and $r$ be the propositions $p :$ You get an $\mathrm{A}$ on the final exam. $q :$ You do every exercise in this book. $r :$ You get an $\mathrm{A}$ in this class. Write these propositions using $p, q,$ and $r$ and logical connectives (including negations). a) You get an A in this class, but you do not do every exercise in this book. b) You get an A on the final, you do every exercise in this book, and you get an A in this class. c) To get an A in this class, it is necessary for you to get an A on the final. d) You get an A on the final, but you don’t do every exercise in this book; nevertheless, you get an A in this class. e) Getting an A on the final and doing every exercise in this book is sufficient for getting an A in this class. f) You will get an A in this class if and only if you either do every exercise in this book or you get an A on the final.

a) You get an A in this class, but you do not do every exercise in this book.
b) You get an A on the final, you do every exercise in this book, and you get an A in this class.
c) To get an A in this class, it is necessary for you to get an A on the final.
d) You get an A on the final, but you don’t do every exercise in this book; nevertheless, you get an A in this class.

Key Concepts

Biconditional Statements

A biconditional statement connects two propositions such that each is both necessary and sufficient for the other, denoted by the operator (?). It is used in situations where the truth of one proposition directly determines the truth of another, encapsulating a two-way conditional relationship.

Necessary and Sufficient Conditions

These terms are used to describe the relationship between propositions. A necessary condition is one that must be met for a certain outcome to occur, whereas a sufficient condition guarantees the outcome if it is met. In logical expressions, necessity is often represented using implication in one direction, and sufficiency in the opposite direction, as seen in parts of the question.

Conditional Statements

Conditional statements assert that if one proposition (the antecedent) is true, then another proposition (the consequent) is also true. They are represented by the implication operator (?) and are crucial for expressing statements about necessity or sufficiency, as seen in parts of the question.

Propositions

A proposition is a declarative statement that is either true or false, but not both. In this question, the statements about getting an A on the final exam, doing every exercise in the book, and getting an A in the class are basic propositions that serve as the building blocks for more complex statements using logical connectives.

Logical Connectives

Logical connectives are symbols or words used to connect two or more propositions to form a compound proposition. These include conjunction (and, ?), disjunction (or, ?), negation (not, ¬), conditional (if... then, ?), and biconditional (if and only if, ?). They help translate verbal statements into formal logical expressions.

Negation

Negation is a logical operation that inverts the truth value of a proposition. In the context of the question, it is used to express that a certain condition is not met, indicating the importance of understanding how to negate propositions or parts of compound statements.
