Consider the following two propositions: P ₁: (p q)P₂:(p q) (( p) q) If the proposition p (( p) q) is evaluated as FALSE, then :
Options
- AP₁ is TRUE and P₂ is FALSE
- BP ₁ is FALSE and P ₂ is TRUE
- CBoth P₁ and P₂ are FALSE
- DBoth P₁ and P₂ are TRUE
Correct answer
C. Both P₁ and P₂ are FALSE
Step-by-step solution
Given propositions P ₁: ( p q ) P ₂:(p q) (( p) q) Required table is shown below. ( array |l|l|l|l|l|l|l|l|l|l|l| p & q & p & q & p q & p ( (p q) & p q & (p q) & p q & p₂ T & T & F & F & T & T & F & T & F & F T & F & F & T & F & F & T & F & T & F F & T & T & F & T & T & T & F & F & F F & F & T & T & T & T & T & F & F & F array ) (p ( p q) ) is (F ) when (p ) is true (q ) is false From table (P₁ ~ &~ P₂ ) both are false
