Let a : ( p r ) ( q s ) and b :( p s ) ( q r ) . If the truth values of a p and q are true and that of r and s are false, then the truth values of a and b are respectively

Options

  1. AT,F
  2. BT,T
  3. CF,F
  4. DF,T

Correct answer

C. F,F

Step-by-step solution

We have p , q T and r , s F aligned & a : ( p r ) ( q s ) ( T F ) ( T F ) & ( T T ) ( F F ) & T F F F F & b :( p s ) ( q r ) ( T F ) ( T F ) T F F aligned
