I can’t see the p in the required query. You
asked for this ~(qv ~r). Symbol V "and" means that the circuit is on or the data will flow when the any one operand is true or "1".
Its truth table is very simple you will have 2^2= 4
combinations
q r ~r (qv ~r) ~(qv ~r)
1 1 0 1 0
1 0 1 1 0
0 1 0 0 1
0 0 1 1 0
The required answer is ~(~qv ~r) = 0 0 1 0
