Chapter 3 - Logic - 3.2 Compound Statements and Connectives - Exercise Set 3.2 - Page 134: 105

Answer

The given compound statement can be written in simple statements as \[p,\text{ and }q\]. Here, \[p,\text{ and }q\] represents three simple statements: p: I am an intellectual. q: I am pessimistic about America. Use the representation to re-write the statement as: If p, q but since not p, not q. ‘If-then’ is represented by the symbol ‘\[\to \]’, ‘But’ is represented by the symbol ‘\[\wedge \]’, and ‘Not’ is represented by the symbol ‘~’. Use the symbols to write the compound statement in symbolic form as: \[\left( \left( p\to q \right)\wedge \tilde{\ }p \right)\to \tilde{\ }q\]
