Prove that `p to (~q vee r) -= ~p vee (~q vee r)` using truth table.

Prove p to (q to r) -= (p wedge q) to r without using truth table.

Prove that Q to P -= P to - Q

Prove that q to p -= ~p to ~q

The dual of ~(p vee q) vee [p vee (p wedge ~r)] is

If the truth value of the statement p to (~q vee r) is false (F), then the truth values of the statements p,q and r are respectively

Draw truth table for p∧-q

Draw truth table for -p∧q

Show that (pvvq) to r -= (p to r) ^^ (q to r)

Construct the truth table for (~p) vee (q wedge r)

Using truth table check whether the statements ~(p vee q) vee (~p wedge q) and ~p are logically equivalent.
