Chapter 3 - Logic - 3.4 Truth Tables for the Conditional and the Biconditional - Exercise Set 3.4 - Page 160: 69

Answer

The truth value of the provided compound statement with the provided condition is false.

Work Step by Step

The provided compound statement in symbolic form is\[q\to \left( p\wedge r \right)\]. Substitute, the truth values for simple statements\[p,q,r\] to determine the truth value for the provided compound statement\[q\to \left( p\wedge r \right)\]. The provided compound statement is conditional statement whose ingredient variables are \[q\] with\[\left( p\wedge r \right)\]. A conditional statement is false only when the truth values of the antecedent is true and the consequent is false. Here, \[\left( p\wedge r \right)\]is a conjunction statement, which is true only when both variables p and \[r\]aretrue. Replace with the truth values of a simple statement:\[\text{T}\to \left( \text{F}\wedge \text{F} \right)\]. This implies the truth values can be rewritten as \[\text{T}\to \text{F}\] or in the simplest form it can be written as \[\text{F}\](false). Therefore, it can be represented in the table form as:
