Chapter 3 - Logic - 3.3 Truth Tables for Negation, Conjunction and Disjunction - Exercise Set 3.3 - Page 148: 67

Answer

The given statement in symbolic form is\[\left( p\vee \sim p \right)\wedge \sim q\], and it gives truth value as true only when \[q\] is false and \[p\]can be either true or false.

Work Step by Step

Assume the statement: \[p\]: You notice this notice. \[q\]: This notice is worth noticing. The given statement first shows the disjunction of the statement\[p\]and negation of the statement \[p\]itself and then conjunction with negation of the\[q\]. Hence, the given statement in symbolic form is\[\left( p\vee \sim p \right)\wedge \sim q\]. The truth table for the given statement is below: From above truth table, it is clear that \[\left( p\vee \sim p \right)\wedge \sim q\]gives truth value as true only when \[q\] is false and \[p\]can be either true or false.
