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
